Description

  The present invention relates to a medical image display apparatus that displays a medical image for interpretation. More specifically, the present invention relates to a medical image display device that receives a selection from images in a plurality of examinations and displays an examination image to be used for comparison when referring to a specific examination image.

  In the medical field, digitization of medical images taken of patients has been realized. The digitized medical image is captured and generated by various medical diagnostic apparatuses (also referred to as modalities) such as an ultrasonic diagnostic apparatus, an X-ray CT apparatus, and an MRI apparatus (Magnetic Resonance Imaging).

  The medical image display device is a device that displays medical images and the like generated by various medical image diagnostic devices. There are various types of medical image display devices depending on purposes such as diagnosis and treatment.

  An operator such as a doctor (hereinafter simply referred to as “operator”) refers to the medical image displayed on the above-described medical image display device and performs image diagnosis based on the medical image. Then, the operator creates a diagnostic report as a result of the image diagnosis. This work is interpretation.

  In this interpretation, an image storage device that stores medical images taken by a medical image diagnostic device and manages them in a database, an image diagnostic workstation that searches for and acquires and displays images, and supports creation of diagnostic reports is used. It is done. When interpreting medical images, the operator operates the diagnostic imaging workstation to acquire and display images from the image storage device. Usually, when interpreting the medical images of the current examination, Interpretation is often performed while comparing with images. Hereinafter, a medical image group generated in one examination is referred to as an “examination image”.

  In addition, the number of images generated by the medical image diagnostic apparatus has been steadily increasing due to the high performance of medical image diagnostic apparatuses and the improvement of diagnostic technology in recent years, and the number of photographs taken for diagnosis is also increasing. In addition, as the number of examinations of patients increases, the number of examination images increases.

  The operator needs to find a desired inspection image to be used for comparison from such a large number of inspection images. Therefore, conventionally, there is a method of displaying an index image composed of thumbnail images and selecting and displaying a desired thumbnail image from the index image. For example, Patent Document 1 discloses a medical image processing apparatus that receives medical image information, performs image processing, displays thumbnails or lists, and displays the displayed thumbnails or lists in the order specified by the operator. Is described.

JP 2004-283325 A

  However, in the conventional configuration in which thumbnail images of inspection images are simply displayed in a selectable manner and the inspection images are displayed in response to the operator's selection, the operator must select the inspection images such as the order in which the inspections were performed. It is necessary to specify an inspection for comparative interpretation from a large number of past inspection images arranged in an order irrelevant to the degree. For this reason, in order to perform comparative interpretation intended by the operator, a long preparation time is required for finding and specifying an inspection image necessary for comparative interpretation in each interpretation, which causes deterioration in interpretation efficiency. Also in the method described in Patent Document 1, since the operator needs to specify the display order, it is necessary for the operator to find an inspection image from among a large number of thumbnail images. It is difficult to achieve specific efficiency. Furthermore, when an image to be interpreted is to be interpreted under certain conditions, such as a pre-operative inspection image, the inspection images that meet the conditions are similarly extracted from a large number of inspection images. It is necessary to search, and it is difficult to perform the interpretation efficiently when the interpretation of the specific condition is repeated many times.

  The present invention has been made in view of such circumstances, and based on information acquired from external information such as an electronic medical record, an examination to be subjected to comparative interpretation from a number of medical images for examination is automatically performed. It is an object of the present invention to provide a medical image display device that is specified and displayed.

  In order to achieve the above object, the medical image display device according to claim 1 specifies the medical image taken by a plurality of examinations for a plurality of patients for each examination. Image storage means for storing together with supplementary information including specific information to be performed, condition storage means for preliminarily storing selection conditions for comparison images of medical images in each of the examinations, and specific examination of a specific patient from the input means An information acquisition unit that receives the medical image display request, reads the predetermined selection condition from the condition storage unit, and acquires external condition information for searching for an examination that matches the read selection condition; , Referring to the image storage means based on the condition information, obtaining a medical image of the examination having the specific information that matches the selection condition of the specific patient, and further, the specific examination An inspection image acquisition unit that acquires a medical image, and a display control unit that causes the display unit to display the medical image of the specific inspection and the medical image of the inspection that matches the selection condition. It is.

  The medical image display apparatus according to claim 1 acquires condition information from the outside, and uses a medical image taken in an examination that matches a stored condition as a comparison image of the medical image taken in the latest examination. It is a configuration to display. As a result, medical images of examinations that meet preset conditions can be automatically displayed as comparative images, and the operator can save time and effort to find and specify examinations for comparative interpretation, thereby improving the interpretation efficiency. Can be improved.

  In addition, when repeated interpretation is performed under certain conditions, medical images of examinations that meet the conditions are automatically displayed as comparison images during interpretation, so that the interpretation efficiency in such cases can be improved. It becomes possible.

Here, the “thickness information” of the electronic medical record is information indicating the usage frequency of the electronic medical record, and the number of accesses is used as an example in the present embodiment. Another example of the thickness information is information indicating an important electronic medical record. Information indicating that this electronic medical record is important is added to the electronic medical record by setting a flag when the doctor considers it important by referring to the electronic medical record. That is, it is in a state with a sticky note indicating that it is important in a paper chart. The more this flag is added, the more frequently referred the electronic medical record is, and it can be said that the thickness information is thick.

  Here, the conditions used as the selection conditions are not limited to the above conditions, and may be other conditions as long as they can express the importance of the inspection as the comparative image. For example, conditions such as an inspection most recently used as a comparison image may be used.

  Furthermore, the condition storage unit 001 stores the priority of each selection condition. In this embodiment, conditions such that the examination immediately before surgery has the highest priority, the examination described in the chart with thick thickness information has the next highest priority, and the examination just before hospitalization has the lowest priority. The storage unit 001 stores the priority of each selection condition.

  Further, the condition storage unit 001 stores items of information necessary to search for examinations that match each condition in association with each condition. For example, in the case of an inspection described in a thick electronic medical chart, the necessary information is specific information of the inspection described in the thick electronic medical chart, and in this embodiment, an item that requires an inspection receipt number Is remembered as In the case of an examination just before hospitalization, the hospitalization date is stored as an item of information that is necessary.

This is specified by referring to the supplementary information of the medical image stored in the image storage unit 002 based on the input receipt number of the examination E or referring to the date of examination of the supplementary information of the medical image. Can be identified.

  In addition, the medical image display apparatus 100 receives from the electronic medical chart management apparatus 102 the reception number of the examination described in the electronic medical chart 112 having the largest number of accesses (thickness information is the thickest) specified by the electronic medical chart management apparatus 102. Based on the receipt number, the supplementary information of the medical image stored in the image storage unit 002 is referred to, and the examination described in the electronic medical chart 112 having the largest number of accesses is identified as examination A.

  The medical image display apparatus 100 receives the operation date 113 specified by the operation information management apparatus 104 and refers to the supplementary information of the medical image stored in the image storage unit 002 based on the operation date 113. The examination that is earlier than the operation date 113 and is closest to the operation date 113 in the examination is specified as examination C.

  The medical image display apparatus 100 has the highest priority of the examination C, which is an examination immediately before the operation, and the examination A described in the electronic chart having the largest number of accesses has a lower priority than the examination C. The medical image of examination C stored in the image storage unit 002 is displayed in the area 702 of the display unit 007, and the thumbnail image of the examination A is displayed in the area 703 of the display unit 007.

  In the above description, only medical images of examinations with the second or higher priority among examinations that match the selection conditions are displayed as thumbnail images, but this is for other examinations that do not match the selection conditions. Images may also be displayed as thumbnail images. In that case, when the operator wants to display an examination other than the examination displayed in the area 702 of FIG. 3 as a comparison image, thumbnail images corresponding to a plurality of examinations displayed using the user interface 006 are displayed. By selecting one of them, the display of the area 702 is changed to the display of the medical image of the selected examination even if it is a medical image of the examination that does not match the selection condition.

  In the above description, the operator selects the comparison image selection condition each time. However, the selection condition may be fixed. In other words, once the information acquisition unit 003 receives an input of the comparison image selection condition, the information acquisition unit 003 continues to use the selection condition until the selection condition is canceled or a new selection condition is input by the operator. Good.

  Here, the flow of setting the selection condition in the configuration in which the selection condition is fixed will be described with reference to FIG. FIG. 5 is a flowchart for setting the selection condition in the configuration in which the selection condition is fixed.

  Step S101: The overall control unit 009 determines whether or not an input for selecting a selection condition has been made by the operator. If the selection condition is selected (Yes), the process proceeds to step S102. If the selection condition is not set (No), the process proceeds to step S103.

  Step S102: The information acquisition unit 003 stores the selected selection condition.

  Step S103: The medical image display apparatus 100 executes a medical image display operation shown in FIG.

  Step S104: The overall control unit 009 determines whether or not to end the operation. The determination of the end of the operation can be made based on, for example, whether or not a stop command is input by the operator. When it is determined that the operation is to be ended (Yes), the overall control unit 009 ends the operation of the medical image display apparatus 100. If it is determined not to end the operation (No), the process proceeds to step S101.

  With such a configuration, when re-interpretation is performed under the same conditions (for example, re-interpretation is performed in comparison with “image of examination performed immediately before surgery”), Since the medical image of the examination that meets the conditions is automatically displayed as a comparative image, it is possible to further improve the interpretation efficiency when repeated interpretation is performed under the same conditions.

  As described above, the medical image display apparatus according to the present embodiment acquires information necessary for searching for an examination that matches a selection condition from the outside, and obtains a medical image of the examination that matches the selection condition. This is a configuration in which it is automatically acquired and displayed together with a medical image of a specific examination requested to be displayed in accordance with its priority. As a result, medical images of examinations that meet preset conditions can be automatically displayed as comparative images, and the operator can save time and effort to find and identify examinations for comparative interpretation, and the interpretation efficiency Can be improved.

  Furthermore, as described above, the medical image display apparatus according to the present embodiment does not have sufficient information for searching for images. For example, the electronic medical record is managed by the electronic medical record management device, the hospitalization information is managed by the hospitalization information management device, and the surgery information is managed by the surgery information management device. Therefore, the medical image display apparatus according to this embodiment needs to acquire necessary information from an external apparatus. That is, the medical image display apparatus has only a selection condition, and is configured to acquire necessary information from an external apparatus and search for a medical image of an examination that matches the selection condition. With such a configuration, the effects of the present invention described above can be realized while maintaining a system in which HIS or the like is introduced.
