JP5522169B2 - Inspection data display device, graph creation method and program - Google Patents

Description

  The present invention relates to an inspection data display device, a graph creation method, and a program.

  A specimen (blood, urine, etc.) collected from a patient is measured for a number of examination items by an examination device. The inspection result is stored as numerical data in a PC (Personal Computer) or the like. This test result is displayed on a PC monitor installed in the examination room or the like and used for informed consent by a doctor.

  In general, the inspection result is often graphed and displayed on a monitor. By graphing the inspection result, it becomes easy to understand the change in the inspection result from the previous measurement date, or to easily compare the inspection items with each other. Further, only the examination items necessary for explanation can be displayed in a graph by a doctor's input operation, and can be explained to the patient.

  In order to make it easy to see the inspection result displayed on the monitor, Patent Document 1 discloses that the normal range is between the upper reference value and the lower reference value set on the graph, and the inspection result is a relative value with respect to the upper reference value and the lower reference value. There is disclosed a technique for displaying a graph using inspection graphs that have different numbers of digits on the same graph.

JP 2001-133293 A

  In Patent Document 1, when the reference value of an inspection item is only an upper limit value (hereinafter referred to as a reference upper limit value) and no lower limit value (hereinafter referred to as a reference lower limit value), the reference lower limit value is set to 0 and the reference lower limit value is set. It is described that the value matches the lower reference value of the vertical axis of the graph. In addition, when only the reference lower limit value exists in the inspection item and there is no reference upper limit value, a value obtained by multiplying the reference lower limit value by a predetermined number is set as the reference upper limit value, and the reference upper limit value is matched with the upper reference value on the vertical axis of the graph. It is described.

  However, if there is no reference lower limit value and a graph is made with the reference lower limit value set to 0, if the inspection result value becomes negative, the point is plotted below the reference range on the graph, although it is normally a normal value. Sometimes. In addition, when there is no reference upper limit value, if a graph obtained by multiplying the reference lower limit value by a predetermined number as the reference upper limit value is a normal value, the point is plotted above the reference range on the graph. There is. In other words, there is a risk of misdiagnosing healthy patients as sick. In addition, when there is no reference upper limit value, when a graph obtained by multiplying the reference lower limit value by a predetermined number of times as the reference upper limit value is displayed, if the reference lower limit value is 0, the reference upper limit value is also 0, so that the relative value cannot be displayed. There is.

  FIG. 21A to FIG. 21D show examples of graphs in which the results 1 to 3 of the inspection items A to C shown in FIG. 17 are displayed using the above prior art. FIG. 21A is a graph in which the inspection result of the inspection item A is displayed as an absolute value. FIG. 21B is a graph in which the inspection result of the inspection item B is displayed as an absolute value. FIG. 21C is a graph in which the inspection result of the inspection item C is displayed as an absolute value. FIG. 21D is a graph in which the inspection results of the inspection items A to C are displayed as relative values. Here, the absolute value-displayed graph refers to a graph displayed using the inspection result value itself without using the relative value.

As shown in FIGS. 21B and 21D, in the inspection item B in which only the reference lower limit value is set, when the reference upper limit value is determined by the technique of Patent Document 1, both the reference upper limit value and the reference lower limit value become 0. Therefore, when considered in terms of absolute value display, all of the inspection result values other than 0 are outside the range of normal values. That is, it looks like an abnormal value. Further, in the relative value display, the graph cannot be displayed because the reference upper limit value matches the reference lower limit value.
Further, as shown in FIGS. 21C and 21D, in the inspection item C in which only the reference upper limit value is set, when the reference lower limit value is determined by the technique of Patent Document 1, the reference lower limit value becomes zero. Therefore, the negative result 3 is plotted outside the normal value range, and appears to be an abnormal value although it is a normal value.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[Configuration of small-scale diagnostic system 1]
FIG. 1 is a block diagram showing a system configuration of a small-scale diagnosis system 1 in the present embodiment.

  The small-scale diagnosis system 1 is applied to a relatively small medical facility such as a practitioner or a clinic. The small-scale diagnosis system 1 includes a modality 2, an image display device 3, a reception device 4, an imager 5, a general-purpose printer 6, a client PC (Personal Computer) 7, and an inspection data management system 8. Each device constituting the small-scale diagnosis system 1 is connected to a communication network (hereinafter simply referred to as “network”) 9 such as a LAN (Local Area Network) via a switching hub (not shown), for example. The image display device 3 is preferably a WS (workstation) provided in an examination room where a doctor is resident. The WS that operates as the image display device 3 may be configured to control activation of each modality 2, processing conditions, and the like.

  In general, DICOM (Digital Image and Communications in Medicine) standard is used as a communication method in a hospital, and DICOM MWM (Modality Worklist Management) or DICOM MPPS (DICOM MPPS) is used for communication between devices connected to a LAN. Modality Performed Procedure Step) is used. Note that the communication method applicable to this embodiment is not limited to this.

[Device configuration of each device of the small-scale diagnosis system 1]
Hereinafter, each apparatus which comprises the small-scale diagnosis system 1 is demonstrated.
The modality 2 is an image generation unit that captures an image of a region to be diagnosed by a patient as a subject and digitally converts the captured image to generate a medical image. A medical image is an image used for interpretation diagnosis in the medical field.

The modality 2 is configured by an ultrasonic diagnostic apparatus (US), an FPD (Flat Panel Detector), or the like. The modality 2 is not limited to this. For example, an endoscope, MRI, or the like may be provided as the modality 2. A modality 2 may be a digital camera or the like that captures the appearance of the body such as the skin.
Furthermore, it is good also as a structure provided with two or more apparatuses of the same kind, for example, including two ultrasonic diagnostic apparatuses. Further, the combination of the devices constituting the modality 2 provided in the small-scale diagnosis system 1 is not limited to the above example.

In the present embodiment, the modality 2 has a function of giving image attribute information such as UID, imaging date / time, examination ID, and examination site to each medical image in a format conforming to the DICOM standard. That is, a medical image is input from the modality 2 to the image display device 3 in a state where these pieces of image attribute information are given.
The UID is a unique ID for specifying a medical image in the small-scale diagnosis system 1. Similarly, a UID is assigned to a specimen test image created in a specimen test image creation process described later.

The modality 2 includes an input unit (not shown) such as a keyboard having character input keys, numeric input keys, and the like, and inputs patient information for specifying a patient to be imaged from the input unit.
Patient information includes patient ID, patient name (kanji), patient name (kana), patient name (ASCII), gender, date of birth, age, etc., medical treatment date, imaging time, reception number, physician in charge, etc. The patient information input in Modality 2 includes, for example, patient ID, patient name (kanji), patient name (kana), patient name (ASCII), gender, and date of birth. is there. Note that it is not necessary to input all of them in the modality 2, and it is possible to not input any patient information. When the modality 2 has a specification for inputting only a patient ID as patient information, the input unit of the modality 2 may be a numeric keypad, for example.

The image attribute information and the patient information are incidental information attached to the medical image generated by the modality 2. The modality 2 transmits a medical image to the image display device 3 via the network 9 in a DICOM file format conforming to the DICOM standard. The DICOM file is composed of an image part and a header part. In the image portion, image data of a medical image is written, and in the header portion, incidental information related to the medical image is written.
If the modality 2 is a device that does not conform to the DICOM standard, such as a digital camera, the modality 2 transmits a medical image in the JPEG format to the image display device 3. In this case, the UID is given to the medical image on the image display device 3 based on the shooting date and time of the medical image.

  The image display device 3 is installed in an examination room, for example, stores a medical image generated by the modality 2 in association with patient information in an image DB (Data Base) 331, or a doctor displays a medical image or the like and interprets it. It is an apparatus for performing diagnosis and the like, and may be provided with a monitor with a higher definition than a monitor (display unit) used in a general PC. The image display device 3 functions as a test data display device that creates and displays a sample test image from the sample test data.

  As shown in FIG. 2, the image display apparatus 3 includes a control unit 31, a RAM 32, a storage unit 33, an operation unit 34, a display unit 35, a communication unit 36, a media drive 37, and the like. 38 is connected.

  The control unit 31 is configured by a CPU (Central Processing Unit) and the like, reads various programs such as a system program and a processing program stored in the storage unit 33, expands them in the RAM 32, and performs a specimen test described later according to the expanded programs. Various processes including an image creation process (see FIG. 10) are executed.

  The RAM 32 forms a work area for temporarily storing various programs executable by the control unit 31 read from the storage unit 33, input or output data, and the like in various processes controlled by the control unit 31.

  The storage unit 33 includes an HDD (Hard Disk Drive), a semiconductor nonvolatile memory, or the like. In addition to storing various programs as described above, the storage unit 33 stores parameters (details will be described later) used in a specimen test image creation process, which will be described later, and an image for adjusting a medical image to an image quality suitable for diagnosis. Processing parameters (look-up table defining tone curves used for tone processing, frequency processing enhancement level, etc.) are stored. Further, the storage unit 33 stores patient information input by the receiving device 4 or the like.

  The storage unit 33 also includes a sample test DB 330 that stores various types of information related to the test results of the sample received from the test data management system 8. The test result of the sample is numerical data of each test item regarding the sample obtained by the test data management system 8. Hereinafter, this numerical data is referred to as specimen test data. The specimen test data is stored in a specific format file (hereinafter referred to as a message) created in CSV (Comma Separated Values) format or the like. The image display device 3 receives a message from the inspection data management system 8 via the network 9. The received message is stored in the specimen test DB 330.

[Message data format]
Hereinafter, the message received by the image display device 3 from the inspection data management system 8 will be described in detail.
FIG. 3A shows an example of the data format of the message. As shown in FIG. 3A, the message includes a “message ID” field, a “sample test ID” field, a “patient information” field, a “collection date / time” field, a “classification” field, a “test item” field, and a “measurement value” field. Etc. In the message, sample test data and patient information related to the sample test data are stored in association with each other. The patient information stored in the message is patient information registered in the examination data management system 8 and may not match the patient information registered in the modality 2 or the image display device 3. For example, in the case of a patient who did not take a medical image with modality 2 and only performed a blood test or urine test with test data management system 8, patient information is not registered in modality 2 or image display device 3, Patient information is registered only in the examination data management system 8. Hereinafter, in order to distinguish, the patient information registered in the modality 2 or the image display device 3 is referred to as patient information A, and the patient information registered in the examination data management system 8 is referred to as patient information B.

In the “message ID” field, an ID uniquely assigned to the message is stored. The “specimen test ID” field stores an ID uniquely assigned to the sample test performed on the patient.
In the “patient information” field, various types of patient information related to the specimen test are stored. Further, the “patient ID” field, the “patient name (kanji)” field, the “patient name (kana)” field, the “patient name (ASCII)”. ) "Field," gender "field, and" birth date "field.
The date and time when the sample is collected is stored in the “collection date and time” field.
The “classification” field stores a classification corresponding to the specimen test data included in the message. The classification is a test corresponding to the collected sample, for example, a blood test if the sample is blood, and a urine test if the sample is urine.
In the “inspection item” field, an inspection item corresponding to the classification is stored. That is, when the value of the “classification” field is “urine test”, each test item (“urine white qualitative”, “urine occult blood”, etc.) for which the result is obtained by the urine test is stored. In the case of “test”, each test item (“total protein”, “inorganic phosphorus”, etc.) for which a result is obtained by the blood test is stored. In the “measurement value” field, numerical data (measurement value) of the inspection result of each inspection item is stored.

  The message is composed of one or a plurality of records, and each record stores sample test data for each test item of the sample classification. For example, as shown in the example of FIG. 3A, the result of the urine test for the patient “Test Taro” and the result of the blood test for the patient “Saburo Yamada” are newly sent to the test data management system 8 at the message transmission timing. If registered, records corresponding to these two inspection results are included in one message.

Even when samples are collected at the same date and time, the date and time when a test result is obtained may vary depending on the classification and the test item. For example, even when blood and urine are collected in one test, the date and time when the blood test results are obtained may be different from the date and time when the urine test is performed. In this case, since the timing at which the blood test result and the urine test result are registered in the test data management system 8 is different, a message including the blood test result and a message including the urine test result are sent to the image display device 3. The transmission timing is also different.
For example, a patient named “Test Taro” performs a blood test and a urine test at “10:00 on June 15, 2008”, and when the message shown in FIG. When the result of the blood test is not given, as shown in FIG. 3A, the message includes only the record corresponding to the test result of the “test Taro” urine test.

  FIG. 3B shows a message transmitted to the image display device 3 when a new inspection result is obtained. The example illustrated in FIG. 3B illustrates a case where the blood test result of “Test Taro” is obtained after the message illustrated in FIG. 3A is transmitted to the image display device 3. Although the blood test results are newly available, they are collected at the same collection date and time as the urine tests for which results have already been obtained and are the same test, so the “sample test ID” field, “patient information” field, and In the “collection date / time” field, the same value as the record of “test Taro” in the message shown in FIG. 3A is stored. In the “Category” field, the value of “blood test” that has been newly obtained this time is stored, and in the “Message ID” field, a value different from the message shown in FIG. 3A is stored.

Returning to FIG. 2, the sample test DB 330 stores a message received from the test data management system 8 via the network 9, a received message table T 1 for storing a message ID for identifying the message, and sample test data included in the message. For example, a parameter table T4 for storing parameters relating to the configuration of the specimen test image. Details of these parameters and parameter table T4 will be described later.
Although a detailed configuration example will be described later, the sample test image is obtained by imaging the sample test data included in the message received from the test data management system 8 based on the parameters stored in the storage unit 33. For example, it is an image obtained by graphing or displaying the sample test data in a table.

FIG. 4 shows an example of the received message table T1. As shown in FIG. 4, the received message table T1 has a “message ID” field, an “not fetched flag” field, and the like.

[Operation of Image Display Device 3]
Next, the operation of the image display device 3 will be described in detail.
FIG. 10 shows a flowchart of the specimen test image creation process executed by the control unit 31 at time intervals stored in the storage unit 33 in advance. The specimen test image creation process is executed in cooperation with the control unit 31 and the program stored in the storage unit 33.

  First, the message stored in the storage unit 33 and the received message table T1 are read (step S1). Next, it is determined whether or not there is new specimen test data in the received message table T1 (step S2). In step S2, the “unacquired flag” field of the received message table T1 read in step S1 is referred to. If there is a record whose value is “unacquired”, a new sample is obtained. If it is determined that there is examination data and all the values of this field are “acquired”, it is determined that there is no new specimen examination data.

  When it is determined that there is new sample test data (step S2; YES), the number of new sample test data is acquired (step S3). The new specimen test data is a specimen test having the same specimen test ID among the specimen test data included in the message in which the value of the “untaken flag” field of the sample test table T1 is “not loaded”. It is a collection of data, and the number of new specimen test data is the number of specimen test IDs with different values included in this message. In the data storage example of the message in FIG. 3B and the data storage example in the sample test table T1 in FIG. 4, the number of new sample test data is one with the sample test ID “40”.

  Next, 1 is substituted into the counter variable i (step S4), and it is determined whether there is unprocessed extracted data (step S5). The unprocessed extracted data is new sample test data in which a sample test image has not been created in step S7 described later among the new sample test data. In step S5, if the counter variable i is larger than the number of new specimen test data, it is determined that there is no unprocessed extracted data. If the counter variable i is equal to or less than the number of new specimen test data, the unprocessed extracted data is determined. It is judged that there is.

  When it is determined that there is unprocessed extracted data (step S5; YES), a captured patient determination process is executed (step S6).

  FIG. 11 shows a flowchart of the acquisition patient determination process executed by the control unit 31 in step S6 of FIG. The acquisition patient determination process is executed in cooperation with the control unit 31 and a program stored in the storage unit 33.

  First, patient information A stored in the storage unit 33 is acquired (step S601). Next, it is determined whether or not the patient ID corresponding to the unprocessed extracted data has been registered (step S602). In step S602, if the patient ID in the “patient ID” field of the message corresponding to the unprocessed extracted data exists in the patient information A stored in the storage unit 33, the patient ID is registered. If it is determined and does not exist, it is determined that the patient ID has not been registered.

  When it is determined that the patient ID has been registered (step S602; YES), it is determined whether or not to compare the patient information A stored in the storage unit 33 with the patient information B corresponding to the unprocessed extracted data. (Step S603). In step S603, a value indicating whether or not to compare patient information is stored in the storage unit 33 in advance, and by referring to this value, it is determined whether or not to compare patient information. This value can be changed by an input from the operation unit 34.

  When it is determined that the patient information A stored in the storage unit 33 is compared with the patient information B corresponding to the unprocessed extracted data (step S603; YES), the patient information A and the patient information B are compared ( Step S604). Specifically, the patient name (kanji), patient name (kana), patient name (ASCII), gender, and date of birth corresponding to the unprocessed extracted data, and the patient information A stored in the storage unit 33 Of these, the patient name (kanji), patient name (Kana), patient name (ASCII), gender, and date of birth of the patient with the matching patient ID are compared.

As a result of the comparison of the patient information in step S604, it is determined whether or not the patient information matches (step S605). If it is determined that the patient information matches (step S605; YES), the sample test image created based on the unprocessed extracted data is set as the sample test image corresponding to this patient (including the patient ID of this patient). ) Is stored in the RAM 32 (step S606).
If it is not determined that the patient information matches (step S605; NO), a return value indicating that the specimen test image created based on the unprocessed extracted data is an indeterminate image is stored in the RAM 32 (step S607).

  On the other hand, when it is not determined that the patient ID has been registered (step S602; NO), it is determined whether or not a new patient is registered (step S608). Here, the registration setting for a new patient refers to a setting for whether or not to newly store (register) patient information B corresponding to unprocessed extracted data as patient information A in the storage unit 33. In step S608, a value indicating whether or not to register a new patient is stored in advance in the storage unit 33, and it is determined whether or not new patient registration is set by referring to this value. This value can be changed by input from the operation unit 34.

If it is determined that registration of a new patient is set (step S608; YES), unprocessed extracted data and corresponding patient information B are stored as new patient information A in the storage unit 33, and the patient information is registered. (Step S609). Next, a return value (including the patient ID of this patient) indicating that the sample test image created based on the unprocessed extracted data is a sample test image corresponding to the registered patient is stored in the RAM 32. (Step S610).
On the other hand, if it is not determined that the registration setting for the new patient is made (step S608; NO), the process proceeds to step S607, and the specimen test image created based on the unprocessed extracted data is set as an indeterminate image. A return value indicating that is stored in the RAM 32.

Returning to FIG. 10, when the capture patient determination process described above is performed, an image creation process is executed (step S7).
FIG. 12 shows a flowchart of the image creation process executed by the control unit 31 in step S7 of FIG. The image creation process is executed in cooperation with the control unit 31 and a program stored in the storage unit 33.

  First, parameters stored in advance in the storage unit 33 are read out and stored in the RAM 32 (step S71). The parameter is a parameter relating to each item such as a graph constituting the specimen test image, and is information indicating, for example, the scale width of the vertical axis of the graph, the test item displayed in the graph, the test item displayed in the table, and the like. is there. Each value of this parameter can be changed in advance by input from the operation unit 34. The parameter whose value has been changed becomes a valid parameter when the specimen image creation process is executed next.

FIG. 13A shows an example of parameters relating to the display form of the graph included in the specimen test image. This parameter includes, for example, an upper limit value and a lower limit value of a normal zone indicating a reference value range on a graph, a maximum number of display days indicating the number of examinations of collection date and time to be displayed simultaneously (hereinafter referred to as the number of extracted data), and a vertical width of the graph Etc.
FIG. 13B shows an example of parameters relating to the inspection item to be displayed in a graph (referred to as a graph display inspection item) and the line color of the graph indicating data of the inspection item. FIG. 13C shows an example of setting values of inspection items to be displayed in a table included in the parameters.
In step S <b> 71, each of the parameters shown in FIGS. 13A to 13C stored in the storage unit 33 is read out and stored in the RAM 32.

  Next, based on the number of extracted parameter data acquired in step S71, records to be displayed as graphs and tables are extracted from the specimen test data table T2 (step S72). Specifically, first, a record in which the patient ID and the patient ID corresponding to the unprocessed extracted data match is extracted from the records stored in the specimen test data table T2. Then, among the extracted records, records corresponding to the number of inspections corresponding to the number of extracted data of parameters are further extracted in the order of the value of the “collection date / time” field. For example, in the parameters shown in FIG. 13A, the number of extracted data is 3. That is, a record of sample test data corresponding to the sample test ID for three times is extracted including unprocessed extracted data.

Next, upper limit / lower limit determination processing is executed (step S73).
The number of test items displayed in a graph is one or more depending on the parameter. To display the sample test data of test items having different reference upper limit values and reference lower limit values on one graph, an absolute value is used. Display is impossible. Therefore, in the image display device 3, a normal zone is set corresponding to a predetermined range (normal zone lower limit value to normal zone upper limit value of the parameter) on the vertical axis of the graph, and the reference upper limit value of each inspection item is normal in the graph. The specimen test data is displayed by setting the scale of the vertical axis for each test item so that the reference lower limit value of each test item matches the lower limit value of the normal zone of the graph at the upper limit value of the zone. Displaying the specimen test data in a graph with the relative value calculated based on the reference value is called relative value display.

  When displaying the relative value, if both the reference upper limit value and the reference lower limit value exist, the graph can be displayed without any problem. However, when only the reference upper limit value or only the reference lower limit value exists, how to display it becomes a problem.

  Therefore, upper limit / lower limit determination processing is executed in step S73, a virtual lower limit is determined for an inspection item in which only the reference upper limit exists, and a virtual upper limit is determined for an inspection item in which only the reference lower limit exists. Thus, the relative value can be displayed even for the inspection item for which the reference upper limit value or the reference lower limit value does not exist.

  FIG. 14 shows a flowchart of the upper limit / lower limit determination processing executed by the control unit 31 in step S73 of FIG. The upper limit / lower limit determination processing is executed in cooperation with the control unit 31 and the program stored in the storage unit 33.

  First, the reference value of the parameter graph display inspection item acquired in step S71 is acquired from the reference value table 332 and set in the arrays A (0) to A (k−1) (step S701). k indicates the number of graph display inspection items as the number of elements. Also, 0 is set to the counter variable m (step S702).

  Next, it is determined whether or not the value of the counter variable m is smaller than the number k of elements in the array A, and when it is determined that the value of m is smaller than the number k of elements in the array A (step S703; YES), the array A ( It is determined whether or not both a reference upper limit value and a reference lower limit value exist in m). If it is determined that both the reference upper limit value and the reference lower limit value exist in the array A (m) (step S704; YES), the process proceeds to step S710.

  If it is determined that the reference lower limit value exists in the array A (m) but the reference upper limit value does not exist (step S705; YES), the virtual upper limit value calculation process is executed (step S706), and the process proceeds to step S710. To do.

  On the other hand, when it is determined that the reference upper limit value exists in the array A (m) but the reference lower limit value does not exist (step S707; YES), the virtual lower limit value calculation process is executed (step S708), and the process proceeds to step S710. Migrate to If any of the determination results in steps S704, S705, and S707 is NO (step S707; NO), the inspection item of the array A (m) is determined as a non-graph display item (step S709), and the process proceeds to step S710. Migrate to

  In step S710, the counter variable m is incremented by 1 (step S710), and the process returns to step S703. If it is determined in step S703 that the value of m is equal to or greater than the number k of elements in array A (step S703; NO), the process proceeds to step S74 in FIG.

  Hereinafter, the virtual upper limit calculation process executed in step S706 and the virtual lower limit calculation process executed in step S708 will be described in detail.

First, the virtual upper limit calculation process will be described.
The absence of the reference upper limit means that all the test results are normal if the inspection result is a value equal to or higher than the reference lower limit. Therefore, if a value equal to or higher than the reference lower limit value is plotted within the reference value range of the graph, that is, within the normal zone, it becomes possible for the doctor or patient who has viewed the graph to correctly recognize the normality / abnormality of the test result. .

Therefore, in the present embodiment, a virtual upper limit value is calculated such that the maximum value of the specimen test data equal to or higher than the reference lower limit value among the specimen test data to be displayed is within the reference value range.
Specifically, a parameter for specifying where the maximum value of the specimen test data equal to or higher than the reference lower limit value in the corresponding test item is plotted in the vertical axis direction in the normal zone is set in advance. The virtual upper limit value is calculated based on the maximum value of the actual specimen test data and the position where the maximum value is plotted.

  The parameter to specify where the maximum value of the specimen test data above the reference lower limit value in the corresponding test item should be plotted in the vertical axis in the normal zone is divided into the normal zone in the vertical axis. Value (referred to as a multiple of the reference value range. For example, 10) and a position where the maximum value of the specimen test data equal to or greater than the reference lower limit value is disposed (result maximum value position. For example, the normal zone is in the vertical axis direction. If it is located at 9/10 from the lower limit when divided into 10 equal parts, it is constituted by 9). These parameters can be set in advance by the user by operating the operation unit 34. Further, it can be changed by operating the operation unit 34. The parameters set by the operation unit 34 are stored in the storage unit 33.

よって、この〔数１〕 を変形することにより、仮想上限値を求めるための下記の〔数２〕を得ることができる。

Between the above two parameters, the maximum value of the sample test data, the reference lower limit value, and the virtual upper limit value, the following relational expression [Equation 1] holds. In the following [Equation 1] to [Equation 4], the upper limit value is the reference upper limit value, the lower limit value is the reference lower limit value, the maximum value of the result is the maximum value of the specimen test data in the test item, and the result The minimum value indicates the minimum value of the specimen test data in the test item.

Therefore, by modifying [Equation 1], the following [Equation 2] for obtaining the virtual upper limit value can be obtained.

According to the above [Equation 2], there is no problem even if the reference value is negative. Even if the maximum value of the result <the reference lower limit value, there is no problem because the virtual upper limit value does not fall below the reference lower limit value because the absolute value is used.
When the maximum value of the result = the reference lower limit value, there is no problem because the virtual upper limit value and the inspection result are pointed on the reference lower limit value if only one inspection result or all of the inspection results are equal to the reference lower limit value. However, when there are a plurality of test results and other test results are below the reference lower limit value, it is necessary to obtain the virtual upper limit value by substituting the next largest test result as the maximum value into [Equation 2].

  Therefore, in the virtual upper limit calculation process in step S706, the specimen test data to be used as the maximum value of the result is determined, and the determined specimen test data is substituted into [Equation 2] as the maximum value to obtain the virtual upper limit value. .

  FIG. 15 is a flowchart of the virtual upper limit calculation process executed by the control unit 31 in step S706 of FIG. The virtual upper limit calculation process is executed in cooperation with the control unit 31 and the program stored in the storage unit 33.

  First, the specimen test data of the test item corresponding to the array A (m) is set to the arrays a (0) to a (j−1) in descending order (step S7001). The element number j indicates the number of examinations to be displayed. Also, 0 is set to the counter variable n (step S7002).

Next, it is determined whether or not the value of n is smaller than the number j of elements of the array a. If it is determined that the value is smaller (step S7003; YES), whether or not the value of the array a (n) is equal to the reference lower limit value. Are determined to be equal (step S7004; YES), the counter variable n is incremented by 1 (step S7005), and the process returns to step S7003.
If it is determined that the value of the array a (n) is not equal to the reference lower limit value (step S7004; NO), the virtual upper limit value is calculated according to the above [Equation 2] (step S7006), and the process is as shown in FIG. The process proceeds to S710.

  When it is determined that the value of n is equal to or greater than the number j of elements in the array a (step S7003; NO), the virtual upper limit value is calculated by the above [Equation 2] (step S7006), and the virtual upper limit value calculation process ends. To do.

Next, the virtual lower limit calculation process will be described.
The absence of the reference lower limit means that all values are normal if the value is equal to or less than the reference upper limit. Therefore, if a value equal to or lower than the reference upper limit value is plotted within the reference value range of the graph, that is, within the normal zone, the doctor or patient who has viewed the graph can correctly recognize the normality / abnormality of the test result.

Therefore, in the present embodiment, a virtual lower limit value is calculated such that the minimum value of the sample test data equal to or lower than the reference upper limit value is within the reference value range among the sample test data to be displayed.
Specifically, a parameter for specifying where the minimum value of the specimen test data below the reference upper limit value in the corresponding test item is plotted in the vertical axis direction in the normal zone is set in advance. The virtual lower limit value is calculated based on the minimum value of the actual specimen test data and the position where the minimum value is plotted.

  The parameter for specifying where the minimum value of the specimen test data below the reference upper limit value in the corresponding test item is plotted in the vertical axis direction in the normal zone is divided into the normal zone in the vertical axis direction. Value (referred to as a multiple of the reference value range. For example, 10) and a position where the minimum value of the specimen test data equal to or higher than the reference upper limit value is disposed (referred to as a result minimum value position. 1), if it is positioned at 1/10 from the lower limit. These parameters can be set in advance by the user by operating the operation unit 34. Further, it can be changed by operating the operation unit 34. The parameters set by the operation unit 34 are stored in the storage unit 33.

よって、この〔数３〕 を変形することにより、仮想下限値を求めるための下記の〔数４〕を得ることができる。

Between the above two parameters, the minimum value of the specimen test data, the reference upper limit value, and the virtual lower limit value, the following relational expression [Equation 3] holds.

Therefore, by modifying [Equation 3], the following [Equation 4] for obtaining the virtual lower limit value can be obtained.

According to the above [Equation 4], there is no problem even if the reference value is negative. Even when the minimum value of the specimen test data> the reference upper limit value, there is no problem because the virtual lower limit value does not exceed the reference upper limit value because the absolute value is used.
When the minimum value of the specimen test data is equal to the upper limit value, there is no problem because the virtual lower limit value and the test result are pointed on the reference upper limit value when only one test result or all of the test results are equal to the reference upper limit value. However, when there are a plurality of test results and other test results are above the reference upper limit value, it is necessary to obtain the virtual lower limit value by substituting the next smallest test result as the minimum value into [Equation 4].

  Therefore, in the virtual lower limit calculation process in step S708, the specimen test data used as the minimum value is determined, and the determined specimen test data is substituted into [Equation 4] as the minimum value to obtain the virtual lower limit value.

  FIG. 16 is a flowchart of the virtual lower limit calculation process executed by the control unit 31 in step S708 of FIG. The virtual lower limit calculation process is executed in cooperation with the control unit 31 and the program stored in the storage unit 33.

  First, the specimen test data of the test item corresponding to the array A (m) is set to the arrays a (0) to a (j−1) in ascending order (step S7011). The element number j indicates the number of examinations to be displayed. Also, 0 is set to the counter variable n (step S7012).

Next, it is determined whether or not the value of n is smaller than the number j of elements in the array a. If it is determined that the value is smaller (step S7013; YES), whether or not the value of the array a (n) is equal to the reference upper limit value. Are determined to be equal (step S7014; YES), the counter variable n is incremented by 1 (step S7015), and the process returns to step S7013.
If it is determined that the value of the array a (n) is not equal to the upper limit value (step S7014; NO), the virtual lower limit value is calculated according to the above [Equation 4] (step S7016), and the virtual lower limit value calculation process ends. To do.

  If it is determined that the value of n is equal to or greater than the number j of elements in the array a (step S7013; NO), the virtual lower limit value is calculated by the above [Equation 4] (step S7016), and the virtual lower limit value calculation process ends. To do.

  For example, when the reference upper limit value, the reference lower limit value, and the inspection results 1 to 3 of the inspection item A, the inspection item B, and the inspection item C are the values shown in FIG. 17, the above upper limit value / lower limit value determination process is performed, When there is no reference upper limit value, the virtual upper limit value is calculated, and when there is no reference lower limit value, the virtual lower limit value is calculated and the inspection results 1 to 3 are plotted on the graphs, respectively, as shown in FIGS. 18A to 18C. A graph (absolute value display graph) is obtained. 18A is a graph showing the inspection item A, FIG. 18B is the inspection item B, and FIG.

  Since the reference upper limit value and the reference lower limit value are predetermined for the inspection item A, as shown in FIG. 18A, the reference upper limit value “20” and the reference lower limit value “0” become the upper limit value and the lower limit value in absolute values. . When the results 1 to 3 are plotted, the position of the inspection result 1 within the reference value range is in the normal zone, the position of the inspection result 2 higher than the reference value is above the normal zone, and the inspection result is lower than the reference value. Position 3 is below the normal zone.

  Since there is no reference upper limit for the inspection result B, as shown in FIG. 18B, the virtual upper limit “40” and the reference lower limit “0” calculated by the upper limit / lower limit determination processing are the upper limits in absolute values. This is the lower limit. Here, the virtual upper limit value calculated with the reference value range equal multiple being 8 and the result upper limit position being 6 is shown. When the results 1 to 3 are plotted, the positions of the inspection results 1 and 2 that are within the reference value range are in the normal zone, and the position of the inspection result 3 that is lower than the reference value is below the normal zone.

  Since there is no reference lower limit for the inspection result C, as shown in FIG. 18C, the reference upper limit “20” and the virtual lower limit “−20” calculated by the above-described upper limit / lower limit determination processing are absolute values. It becomes the upper limit value and the lower limit value. Here, the hypothetical lower limit value determined by setting the reference value range equal multiple as 8 and the result upper limit position as 2 is shown. When the results 1 to 3 are plotted, the positions of the inspection results 1 and 3 that are within the reference value range are in the normal zone, and the inspection result 2 that is higher than the reference value is above the normal zone.

  When the inspection results A to C are displayed as relative values based on the absolute value displays shown in FIGS. 18A to 18C, the graph shown in FIG. 18D is obtained.

  Thus, by calculating the virtual upper limit value for the inspection item for which the reference upper limit value does not exist and the virtual lower limit value for the inspection item for which the reference lower limit value does not exist by the above upper limit / lower limit determination process, the inspection result within the reference range Values can be displayed within the normal zone, and test result values outside the reference range can be displayed outside the normal zone.

When the upper limit / lower limit determination processing ends, a graph or a table is created based on the parameter, the reference upper limit value or the virtual upper limit value, the reference lower limit value or the virtual lower limit value acquired in step S71 (step of FIG. 12). S74). For the graph, a normal zone is set corresponding to a predetermined range on the vertical axis (here, normal zone lower limit value and normal zone upper limit value −1 to 1), and a reference upper limit for each inspection item to be displayed. The scale of the vertical axis of the graph is set for each test item so that the value or virtual upper limit value matches the upper limit value of the normal zone and the reference lower limit value or virtual lower limit value matches the lower limit value of the normal zone. A graph is created by plotting.
Next, a specimen test image and a thumbnail image including the created graph and table are created and stored as a temporary file in the RAM 32 (step S75).

FIG. 19 shows an example of the specimen test image 352 created in step S75. The specimen test image 352 includes a collection date / time 201, a graph legend 202, a graph 203, a test item list 204, a table 205, and the like.
The collection date / time 201 is the value of the “collection date / time” field of the message corresponding to the unprocessed extracted data. The graph legend 202 displays a graph legend corresponding to the parameter graph display inspection item. The graph 203 is displayed by drawing a graph of the inspection item corresponding to the parameter graph display inspection item with a line of a predetermined color. The examination item list 204 shows a list of specimen examination data. The table 205 displays a table of inspection items corresponding to parameter table inspection items.

  Returning to FIG. 12, parameters relating to the created specimen test image are created and stored as a temporary file in the RAM 32 (step S76). The parameter relating to the specimen test image is the parameter determined in step S71.

  When the image creation process ends, the process returns to FIG. 10, and it is determined whether or not a specimen test image having the same collection date as the specimen test image created in step S7 has been created (step S8). Specifically, in the sample test DB 330, a message corresponding to the unprocessed extracted data for which the sample test image has been created in step S7 and the message having the same values in the “patient ID” field and the “collection date” field are searched. In the received message table T1, if there is a record in which the value of the “unacquired flag” field associated with the message ID of the retrieved message is “acquired”, the sample on the same collection date If it is determined that a test image has been created and there is no such record, it is determined that a sample test image on the same collection date has not been created.

  When it is determined that the sample test image on the same collection date has been created (step S8; YES), the UID of this sample test image is acquired from the image information table T3, and the parameter table T4 is referred to. It is determined whether or not this specimen test image is unread (step S9). Specifically, among the records of the parameter table T4 (details will be described later), the record corresponding to the UID of the created specimen test image is referred to, and the value of the “image unread flag” field of this record is referred to Then, it is determined whether or not the created specimen test image is unread. Note that the UID of the specimen test image on the same collection date is a patient ID whose “patient ID” field and “imaging date” of the image information table T3 correspond to this specimen test image (that is, corresponding to unprocessed extracted data). And the “UID” field of the record that matches the collection date and time is referred to.

  When it is determined that the sample test image on the same collection date has not been read (step S9; YES), unprocessed extracted data in the sample test table T2 and various information corresponding to the unprocessed extracted data (sample test ID) , Patient information A, etc.) are stored (step S10).

  FIG. 5B shows an example of a specimen test table T2 in which unprocessed extracted data is stored. The example shown in FIG. 5B is an unprocessed in step S10 in the case of the sample data storage example shown in FIG. 3B and the sample data storage example of the received message table T1 shown in FIG. This shows an example in which the extracted data is stored. The specimen test data of “blood test” of “Test Taro” shown in FIG. 4 is stored in the specimen test table T2.

Next, the specimen test image and the thumbnail image created in step S72 are overwritten and saved in the storage unit 33 (step S11). Specifically, the specimen test image and thumbnail image of the UID acquired in step S9 are overwritten and saved by the specimen test image and thumbnail image created in step S72.
The parameter is updated by being stored in the parameter table T4 together with the parameter stored in the RAM 32 in step S71 (step S12).

FIG. 20 shows an example of the parameter table T4. As shown in FIG. 20, the parameter table T4 includes a “UID” field, an “image unread flag” field, a “determined flag” field, a “graph display inspection item” field, a “table inspection item” field, and a “normal zone upper limit value”. ”Field,“ normal zone lower limit value ”field,“ maximum display days ”field,“ vertical width ”, and the like. The parameter table T4 stores parameters of each specimen test image created by the specimen test image creation process. The parameter table T4 is stored with the UID, the image unread flag, and the confirmation flag added to the parameters acquired in step S71.
Of the values stored in the “graph display inspection item” field shown in FIG. 20, the values shown in parentheses are the colors of the graph lines.

The UID is a UID assigned to the created specimen test image.
The image unread flag is a flag for identifying whether or not the specimen test image corresponding to the record is displayed on the display unit 35. When the sample test image displayed in the image display field 78 of the viewer screen 351 is displayed on the display unit 35 by clicking the input from the operation unit 34 or the like, the image unread flag of this sample test image is changed from “unread” to “ Changed to “Read”.
The confirmation flag is a flag for identifying whether or not the examination included in the created specimen examination image is confirmed. Here, the confirmation of the examination indicates whether or not the examination has been explained to the patient. For example, when the sample examination image displayed on the viewer screen 351 is output by the image output button 82b, As the inspection is explained, the confirmation flag is changed from “before confirmation” to “confirmed”.
In step S12, the parameter table T4 is referred to, and each parameter stored in the record corresponding to the specimen test image before being overwritten in step S11 is replaced with the parameter stored in the RAM 32 in step S73.

  Returning to FIG. 10, various pieces of information relating to the specimen test image overwritten and stored in step S11 are registered in the image information table T3 (step S13). Specifically, registration is performed by overwriting various types of information (test site, etc.) related to the specimen test image of the record in which the UID acquired in step S9 matches the “UID” field of the image information table T3.

  On the other hand, when it is not determined that the sample test image on the same collection date is already in the storage unit 33 (step S8; NO), it is not determined that the sample test image on the same collection date is unread (step S9; NO). The unprocessed extracted data and various information (sample test ID, patient information A, etc.) corresponding to the unprocessed extracted data are stored in the sample test table T2 (step S14). A UID is newly assigned to the specimen test image created in step S7, and is stored in the storage unit 33 according to the return value of step S7 together with the thumbnail image (step S15). If the return value stored in the RAM 32 in the captured patient determination process in step S6 indicates “corresponding patient data” or “registered patient data”, the specimen test image is stored in a predetermined folder of the image DB 331. , “Undetermined image” is stored in the undetermined image area of the image DB 331. Next, the parameter stored in the RAM 32 in step S71 is associated with the UID assigned to the specimen test image and stored as a new record in the parameter table T4, so that the parameter is added (step S16). .

  Next, various pieces of information relating to the specimen test image newly stored in step S15 are registered in the image information table T3 (step S17). Specifically, a new record is created in the image information table T3, and the UID assigned in step S15 and various information (patient ID, etc.) related to the specimen test image are associated with each other and stored in this record. If the return value stored in the RAM 32 in the captured patient determination process in step S6 indicates “corresponding patient data” or “registered patient data”, the patient ID of this patient is stored, and the “indeterminate image” ", No value is stored in the patient ID. The “image storage destination” stores the location (storage destination) where the image is stored in step S11 or step S15.

Next, the counter variable i is incremented by 1 (step S18), and the process returns to step S5.
On the other hand, if it is not determined that there is unprocessed extracted data (step S5; NO), the unacquired flag of the received message table T1 corresponding to the message ID of the unprocessed extracted data is set to “acquired” (step S19). ), The process ends.
If it is not determined that there is new specimen test data (step S2; NO), the process ends.

  As described above, according to the small-scale diagnosis system in the present embodiment, the control unit 31 of the image display device 3 has only the reference lower limit value and the reference upper limit value does not exist in the inspection item to be displayed. A virtual upper limit value is calculated such that the maximum value of the specimen test data equal to or greater than the reference lower limit value is within the reference value range. Further, when only the reference upper limit value exists and the reference lower limit value does not exist in the test item to be displayed, a virtual lower limit value is calculated such that the minimum value of the specimen test data equal to or lower than the reference upper limit value is within the reference value range. The graph is such that the reference upper limit value or the virtual upper limit value of the inspection item to be displayed matches the upper limit value of the normal zone, and the reference lower limit value or the virtual lower limit value of the display target inspection item matches the lower limit value of the normal zone. A graph indicating the sample test data of the test item to be displayed is created and displayed on the display unit 35.

  Therefore, when the test results are displayed in a graph using relative values, even if the test item has no reference upper limit value or the test item has no reference lower limit value, the sample test data within the reference range is correctly placed in the normal zone. Can be displayed. As a result, it is possible to prevent the risk of misdiagnosing healthy patients as ill.

  Further, when there is no reference upper limit value, the user can set in advance by the operation of the operation unit 34 which position in the vertical axis direction within the normal zone to plot the maximum value of the specimen test data equal to or higher than the reference lower limit value. As a result, it is possible to display the maximum value of the patient's result in a position that seems to be the best when the doctor shows the graph to the patient within the range of the normal zone.

  In addition, when there is no reference lower limit value, the user may set in advance by the operation of the operation unit 34 which position in the vertical axis direction within the normal zone the minimum value of the specimen test data equal to or lower than the reference upper limit value is plotted. As a result, it is possible to display the minimum value of the patient's result at a position that seems to be the best when the doctor shows the graph to the patient within the normal zone.

In addition, the description in this Embodiment mentioned above is an example of the suitable small-scale diagnosis system which concerns on this invention, and is not limited to this.
For example, in the present embodiment, the specimen test image creation process is periodically executed, but may be executed by an input from the operation unit 34. For example, the sample test data stored in the sample test data table T2 is displayed as a graph on the display unit 35, and the graph displayed on the display unit 35 is saved as a sample test image by an input from the operation unit 34. May be. In this case, each parameter displayed in a graph is stored in the parameter table T4.

  Further, in step S5 of the specimen test image creation process shown in FIG. 10, it is determined whether there is unprocessed extracted data using the counter variable. However, the specimen test data for which the specimen test image is to be created is determined. It is sufficient if it can be determined whether or not there is another method. For example, EOF (End Of File) data may be attached to the last record of the new specimen test data, and it may be determined whether there is unprocessed extracted data based on this data.

Further, the unincorporated flag corresponding to the message for which the specimen test image has been created is updated in step S19. However, it is only necessary that the unincorporated flag can be updated when the specimen test image for the message has been created. The present embodiment is not limited to the example.
In the present embodiment, the image unread flag and the confirmation flag are stored in the parameter table T4. However, based on the values stored in the storage unit 33, whether or not the specimen test image is unread or has been confirmed. What is necessary is just to be able to judge whether or not, and is not limited to this. For example, the image unread flag and the confirmation flag may not be stored in the parameter table T4, but may be managed in another table.

The reference upper limit value or the virtual upper limit value of the inspection item to be displayed matches the upper limit value of the normal zone, and the reference lower limit value or the virtual lower limit value of the inspection item to be displayed matches the lower limit value of the normal zone. A graph creation means for creating a graph indicating an inspection result value of the inspection item to be displayed by setting a scale of the vertical axis of the graph to
Function as operating means for presetting at which position in the vertical axis direction within the normal zone the minimum value of the inspection result value below the reference upper limit value is plotted;
The virtual lower limit value calculating unit calculates the virtual lower limit value based on the reference upper limit value, the minimum value of the inspection result value, and the position of the minimum value of the inspection result value set by the operation unit .
