  The communication control unit 1h is a unit such as a LAN card or a modem, and is a unit that enables the medical diagnostic apparatus 1 to be connected to a communication network such as the Internet or a LAN. In particular, for example, various management built in medical institutions such as hospital information management system (HIS), radiation department information management system (RIS), medical image management system (PACS: Picture Archiving Communication System) Connected with the system. Data transmitted / received to / from the communication network via the communication control unit 1h is transmitted / received to / from the CPU 1a via the input / output interface 1d and the bus 1e as an input signal or an output signal.

  The storage means 1i is composed of a semiconductor or a magnetic disk, and stores programs and data executed by the CPU 1a. The removable disk 1j is an optical disk or a flexible disk, and signals read and written by the disk drive are transmitted to and received from the CPU 1a via the input / output interface 1d and the bus 1e.

  In the storage unit 1i of the medical diagnostic apparatus 1 according to the embodiment of the present invention, for example, various information for creating a check list and various information for configuring an examination stage are stored as a database or text file information. The In addition, the checklist display unit 2 is mounted on the medical diagnostic apparatus 1 by reading and executing a checklist creation / update program or the like by the CPU 1 a of the medical diagnostic apparatus 1.

  In the following, a case where a checklist creation update program or the like is stored in the storage unit 1i will be described as an example. However, this checklist creation update program or the like may be stored in the removable disk 1j.

  As shown in FIG. 2, the check list display means 2 includes a receiving means 2a for receiving information from other devices connected to a network, for example, via an input means 1f and a communication control means 1h, and a patient information collecting means. 2b, inspection information collection means 2c, check list creation means 2d, inspection stage management means 2e, display content update means 2f, and transmission means 2g for transmitting the updated display contents to display means 1g. The

  The patient information collecting means 2b is for collecting information on a patient to be examined using the medical diagnostic apparatus 1. Examples of patient information include “patient ID”, “age”, “sex”, “visit category”, “medical history”, “physical condition”, and the like. For example, when the patient ID is input, the patient information is connected to the above-described HIS, RAS, and PACS via the communication control unit 1h, and the patient information recorded in the management system can be collected. Further, it may be collected by directly inputting to the medical diagnostic apparatus 1.

  The examination information collecting unit 2c collects information on examinations performed on a patient to be examined in the medical diagnostic apparatus 1. Examples of the examination information include examination type, examination date and time, requested department, requested doctor, and the like. This examination information is inputted by an examination engineer or the like from the input means 1 f of the medical diagnostic apparatus 1. Further, in the case where a test performed in the past is performed again, the test information may be collected from another medical diagnostic apparatus or terminal via the communication control unit 1h.

  The check list creation means 2d performs examination based on patient information and examination information transmitted from the patient information collection means 2b and examination information collection means 2c, and basic check list information stored in the storage means 1i. Create a checklist tailored to the target patient.

  The inspection stage can be divided into, for example, “reservation stage”, “imaging stage”, “observation stage”, and “filing stage”, and items constituting the screen displayed on the display means 1g according to each stage. It is decided in advance. The inspection stage management means 2e manages each inspection stage and items displayed on the stage, and manages them in association with each other. Further, according to the progress of the inspection, information on the inspection stage on which the check list is displayed is transmitted to the display content update means 2f.

  The display content updating unit 2f selects a check list to be displayed on the inspection stage based on the inspection stage information transmitted from the inspection stage management unit 2e from the check list generated by the check list generation unit 2d. Then, it is transmitted to the display means 1g via the transmission means 2g and displayed. In addition, when information on the transition of the inspection stage is obtained, the display content is updated again in the check list suitable for the inspection stage.

  Next, the flow of creating and displaying a check list according to the progress of the inspection will be described with reference to the flowchart shown in FIG. 3 and the drawings in FIG.

  When a patient is inspected by the medical diagnostic apparatus 1, an examination reservation screen as shown in FIG. 4 is first displayed on the display means 1g. In the following, for the convenience of explanation, drawings showing screens displayed on the display means 1g are used. However, these drawings are merely examples of screens, and screen layouts and items constituting the screens are as follows. It can be arbitrarily determined.

  In the screen example shown in FIG. 4, buttons indicating the respective inspection stages are provided on the left side of the screen. Since this screen is an inspection reservation screen, the “reservation” button is highlighted. Here, the description will be made on the assumption that there is a patient who has already made an examination reservation, rather than making an examination reservation.

  A patient to be examined is selected from the examination target patients displayed on the examination reservation screen (ST1). When the patient is selected, although not shown in FIG. 4, for example, the display is displayed so that the selection becomes clear, for example, the display is reversed. In this examination reservation screen, only the patient name, patient ID, and doctor in charge are displayed, but other patient information may be displayed. In the embodiment of the present invention, when a patient is selected on this examination reservation screen, the patient information collection means 2b calls information on the patient selected from various management systems such as HIS built in the hospital. (ST2).

  When the patient information is collected, the display screen is switched to the imaging stage screen shown in FIG. In this screen, the patient selected as the examination target (“Toshiba Hanako” in FIG. 5) and the patient information (age and sex) are displayed. Based on this patient information, the examination information collection means 2c next sets and collects examination contents (ST3). For example, in FIG. 5, an “examination type” column is provided below the column indicating patient information, and “contrast examination” is selected from the “examination type”. Further, a column for selecting “adult”, “children”, and the like, and a column for selecting “examination site” are provided beside the “imaging plan” column. In FIG. 5, “adult” and “chest” are respectively provided. Is selected. In this way, when the inspection content is set, the inspection information is transmitted from the inspection information collecting unit 2c to the check list creating unit 2d as inspection information.

  The check list creation means 2d acquires the patient information and the examination information sent from the patient information collection means 2b and the examination information collection means 2c, respectively (ST4). The check list creation means 2d obtains a basic check list from the storage means 1i based on the acquired patient information and examination information (ST5), and creates a check list for each examination stage (ST6). As shown in FIG. 6, this basic check list is stored in advance as database or text file information in the storage means 1i.

  For example, in the check list shown in FIG. 6, from the left column to the right column, “check item”, “check condition”, “stage classification”, “impact level classification”, “display level classification”, “application”. Items are provided.

  As the “check items”, for example, items such as “presence / absence of pregnancy”, “renal function level”, “examination purpose”, and the like are provided. These are items that are directly displayed as a check list at each inspection stage and to be checked. In the “check condition”, a condition as to whether or not to display the check items as a list is specified. For example, if the check item is “pregnancy presence / absence”, it is displayed when “sex” of “patient information” is “female”. Further, if the check item is “confusion check”, it is displayed when “physical condition” of “patient information” is “severe”.

  “Stage classification” designates an inspection stage for displaying a checklist. For example, when “visit category” of “patient information” as “check condition” is “outpatient”, “confirmation letter” is listed as a check item in the check list displayed in “reservation stage”. Note that the inspection reservation screen shown in FIG. 4 does not show a check list that uses the introduction letter confirmation as a check item.

  “Impact level classification” indicates the level related to safety in the check work. For example, in FIG. 6, “critical items related to life” is “A”, “critical items” is “B”, and “others” Item "is classified as" C ". For example, “WL (window level) setting” or the like is an item that is set to adjust the gradation of the captured image when observing the captured image, and does not threaten the safety of the patient or the operator. Therefore, the importance level is low and is classified as “C”.

  “Display level classification” indicates the proficiency level of the operator with respect to the medical diagnostic apparatus. For each item shown in FIG. 6, for example, numbers “1” to “3” are displayed. In the embodiment of the present invention, “1” is an essential item, and “2” is an item displayed when the beginner mode is selected. “3” is an expert mode.

  “Application” is not only displayed by a check list for each check item, but also allows other notification methods to be selected as a display method. For example, when the “check item” is “name confirmation”, not only is it displayed as a check list, but if the “speech reading function” as an application is selected, the “speech reading function” provided in the medical diagnostic apparatus 1 Can be set to read the patient's name by voice. However, for example, “N / A” in which “application” is not set depending on the check item, such as “presence / absence of pregnancy”.

  As described above, the check list creation means 2d uses the basic check list stored in the storage means 1i in advance to create a check list suitable for each inspection stage as shown in FIG. FIG. 7 is a check list created for this patient, for example, from “Toshiba Hanako” displayed in FIG. 5 and its patient information (age and gender) and “examination type”. In FIG. 7, “pregnancy presence”, “renal function level”, and “examination purpose” are listed as check items displayed as a check list in “imaging stage”. In “observation stage”, “WL setting”, “ Two check items “WW Settings” are displayed in the check list. Note that the created check list for each examination stage may be stored in the storage unit 1i in association with patient information and examination information, for example.

  Then, the display content update unit 2f obtains information on the inspection stage from the inspection stage management unit 2e, and displays a check list that matches the displayed screen based on this information (ST7). For example, in FIG. 5 representing “shooting stage”, a check list is displayed at the lower right of the screen example. This check list includes two types of check items in addition to the above “presence / absence of pregnancy”.

  If an application is set in advance when the checklist is displayed, the application is activated. For example, if the “name confirmation” check item in the “imaging stage” is on the checklist and the “speech reading function” is selected as the application, the checklist is displayed and the patient's name is displayed. Read aloud.

  Further, as the inspection progresses, it is also possible to display the check list displayed at the inspection stage that has been performed so far. In this way, by displaying all the items that have been checked so far, it is possible to further prevent check omissions.

  The operator further formulates a shooting plan based on this checklist. For example, in the “imaging stage” screen shown in FIG. 5, a column of “imaging plan” is provided, and a plan for imaging (inspection) for the patient is input here. In formulating an imaging plan, for example, if the patient to be examined has undergone a similar examination in the past, by pressing the “Refer to past image” button provided on the right side of the patient information column. It is also possible to display a desired image by connecting a past image to the PACS or the like via the communication control means 1h.

  Further, on the left side of the “imaging plan” column, information on whether the patient to be examined is an adult or a child and information on the examination site is displayed. For example, in the case of a medical diagnostic apparatus using X-rays, the amount of X-rays to be exposed by “adults” and “children” must be changed. There is. By displaying the checklist, it is possible to formulate an imaging plan that takes into account patient safety as much as possible.

  FIG. 8 is a schematic diagram showing an example of a screen in the “observation stage”. Since the “observation stage” is a stage for observing a photographed image, the photographed image is displayed at the bottom of the screen. Furthermore, here, two check items “WL setting” and “WW setting” are displayed on the check list from the check list created for this patient shown in FIG.

  On the check list, a column for indicating whether or not the check has been made is provided, and a mark indicating that the check has been made is written in the checked item. In the first place, the checklist is displayed for each examination stage by displaying a checklist tailored to the patient to be examined, thereby eliminating the check omission in the operator's examination and ensuring operational safety. This is for the purpose of ensuring safety. Therefore, if it is possible to move to the next inspection stage without checking all necessary check items, it becomes difficult to ensure the safety of the operator and the patient.

  Therefore, the display content updating unit 2f determines whether all necessary items are checked on the displayed check list (ST8). If it is determined that it is not checked, the screen does not transition to the next inspection stage, for example, as shown in FIG. 9, a “warning dialog” is displayed on the screen, and the transition to the next inspection stage is made. To prevent.

  In addition, here, there is also an idea that regarding the determination of whether or not to shift the inspection stage, for example, in a state where all the check items are not checked, the transfer of the inspection stage is always prevented. Of course, it is also possible to determine whether or not to move to the next inspection stage based on such a concept.

  Further, whether or not all necessary items on the check list are checked may be used as a criterion for determination. The reason why such a criterion is adopted is that, as shown in the check list of FIG. 6 or FIG. 7, the item of “impact level classification” is provided in the embodiment of the present invention. . For example, if the level is “C” and there is no problem regarding the safety of the operator and the patient, even if the check item is not checked, the process proceeds to the next inspection stage. No problem. Therefore, all the necessary items on the checklist are checked in consideration of “impact level classification” in each check item, that is, all items whose “impact level classification” is, for example, “A” and “B” are checked. If it is, the transition to the next inspection stage is permitted without displaying the warning dialog.

  Further, as a means for notifying the operator that all necessary items on the check list have not been checked, a method of displaying a “warning dialog” as in the embodiment of the present invention (see FIG. 9). For example, notification by voice may be used.

  When it is determined that all necessary items have been checked, the display content update unit 2f determines whether the screen has changed, that is, whether the screen has shifted to the next inspection stage (ST9). If it is determined that the next inspection stage has been entered, a checklist suitable for the inspection stage is selected from the checklist created by the checklist creation means 2d and the display content is updated.

  When the inspection is completed, the inspection stage shifts from the “observation stage” to the “filing stage”, and the image obtained by the inspection is stored in the medical diagnostic apparatus 1 by using the storage means 1i or the communication control means 1h to another management system. And filing (ST10). FIG. 10 is a schematic diagram showing an example of a screen in the “filing stage”. This screen is provided with “storage target data” for displaying patient information of the patient to be examined and “image display column” for confirming which captured image regarding the patient is to be filed. In the “storage destination” field, it is possible to select which medical diagnostic apparatus or management system stores the image.

  When filing, it is also possible to issue a filming instruction to devices such as imagers connected to the network at the same time.

  Then, it is determined whether or not the examination for the patient is completed by the display content updating means 2f (ST11). If the examination has not been completed, that is, in this case, the process has been completed until filing. Therefore, when examining the next patient, the examination is performed again according to the flow shown in Step 1 and the subsequent steps.

  When the examination is completed and there is no patient to be examined next, all examination operations in the medical diagnostic apparatus 1 are completed.

  Thus, when a patient is inspected using a medical diagnostic apparatus, a checklist listing items that need to be checked for each inspection stage is displayed, so that the safety of the inspection for the operator of the medical diagnostic apparatus and the patient is displayed. It is possible to provide an examination safety ensuring system capable of ensuring the above and a medical diagnostic apparatus equipped with the system.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description of the same components is omitted because it is duplicated.

  In the second embodiment, as shown in FIG. 11, an operator information collection unit 2h is added to the check list display unit 2 in the first embodiment.

  The operator information collecting unit 2h collects information about the operator such as an operator ID input by the operator of the medical diagnostic apparatus 1. The collected operator information is referred to in the check list creation means 2d when the check list is created, so that the check list corresponding to the ability of the operator can be displayed.

  More specifically, for example, an operator information list as shown in FIG. 12 is stored in the storage unit 1i. In this operator information list, items “ID”, “operator name”, “attribute”, “skill level”, and “check list” are provided from the left column to the right column.

  “ID” is a column in which an ID number given to an operator who operates the medical diagnostic apparatus 1 is represented, and the name of the operator having this ID is shown in the “operator name” column. . The “attribute” specifies a group for managing the authority of the operator to operate the medical diagnostic apparatus 1. Examples of the “attribute” include “beginner operator”, “advanced operator”, “administrator”, and the like. In the operator information list shown in FIG. 12, the attributes “A” to “C” are represented, for example, indicating that the authority is higher from “C” to “A”.

  The “skill level” indicates a level of skill of the operator in operating the medical diagnostic apparatus 1. Here, like “attribute”, it shows that the student has a higher proficiency level from “C” to “A”. With regard to this “skill level”, for example, the number of operations required for each skill level, the working day, and the like are determined, and the skill level increases as the standards are met.

  The “check list” defines the check items listed in the check list to be displayed on the screen of each inspection stage according to the levels expressed in the items “attribute” and “skill level”. In this operator information list, the number of check items raised on the check list from “1” to “5” increases.

  Therefore, for example, the operator who is given “ID: 1111” is accustomed to the whole examination because “attribute” is “A” and “skill” is “C”. It can be determined that the user is not used to the examination using the medical diagnostic apparatus 1. Therefore, check items corresponding to the stage “2” are displayed on the check list. Further, for example, an operator who is given “ID: 1385” has “B” in “Attribute” but “A” in “Proficiency”. Since it can be determined that the user is used, check items corresponding to the stage “1” are displayed on the check list.

  In this way, in addition to the effects achieved in the first embodiment described above, the checklist is displayed in consideration of the information of the operator who operates the medical diagnostic apparatus 1, thereby improving the efficiency of the examination. In addition, it is possible to provide an examination safety ensuring system that can be used for educational purposes of an operator, and a medical diagnostic apparatus equipped with the system.

  In the second embodiment, the operator information stored in the storage unit 1i is used in advance. However, when the operator operates the medical diagnostic apparatus 1, the operator information is input at the same time. You may make it input own "attribute" and "skill level". In addition, when inputting the operator information of the operator who operates the medical diagnostic apparatus 1, in addition to the input of the ID and the like described above, a method using a biometric feature such as the fingerprint of the operator or an IC card is used. A method or the like can also be adopted.

  As described above, the medical diagnostic apparatus has been described without specific specification. Examples of the medical diagnostic apparatus include an X-ray diagnostic apparatus, a CT (computed tomography) apparatus, an ultrasonic diagnostic apparatus, and a magnetic apparatus. Examples thereof include a resonance diagnostic apparatus, a gamma camera, and PET (positron-emission tomography), and the present invention can be applied to any of these medical diagnostic apparatuses.

  In addition, for the convenience of explanation, drawings with display items and display contents are used. However, these display items and display contents can be arbitrarily set, and are limited to the display items and display contents shown in the drawings. It is not something.
