  The interpretation report creation unit 1212 executes an interpretation report creation function. When the instruction marker IM is set, the interpretation information indicated by the instruction marker IM is displayed in the observation column of the interpretation report. create. Details will be described later. The interpretation report creation unit 1212 is an example of an embodiment of an interpretation report creation unit in the present invention.

  As shown in FIG. 3, medical image data 21, patient / examination information data 22, and definition information data 23 are stored in the medical image server 2. The medical image data 21 is DICOM data photographed by the modality 3 and includes, as DICOM header information, a Study Instance UID, a Series Instance UID, a SOP Instance UID, and the like. The Study Instance UID is an ID of an examination, the Series Instance UID is an ID indicating which series of images, and the SOP Instance UID is an ID indicating an image number of a certain series. For example, as shown in FIG. 4, when a certain inspection includes photographing of a scout image, photographing of a cross-sectional group I, and photographing of a cross-sectional group II, the scout image is photographed in Series 1, and the photographing of the cross-sectional group I in Series 2. The imaging for the cross section group II is set as Series3. In this case, the Study Instance UID is an ID of the examination composed of the above-described Series 1 to 3, and the Series Instance UID is an ID indicating which series of the Series 1 to 3. The SOP Instance UID is an ID indicating an image number assigned to an image in each series. For example, when Series 2 includes n images, an ID indicating image numbers 1 to n is an SOP Instance UID.

  The Series Instance UID and the SOP Instance UID are information for specifying a medical image from a plurality of medical images obtained in one examination for the same subject, and the implementation of the specific information of the medical image in the present invention. It is an example of a form.

  The patient / examination information data 22 is data of patient information and examination information of the medical image data 21. Patient information is information, such as a patient's name and patient ID, for example. In addition, the examination information is, for example, information on an examination from which a medical image is acquired, and is, for example, information such as an examination date, an examination modality, and an examination part.

  As shown in FIG. 5, the definition information data 23 includes a plurality of types of indication markers IM1, IM2, IM3,... With different display forms, and information on the contents of the observation columns indicated by the indication markers IM (finding information). ). Since the findings differ depending on the diagnosis part, the definition information data 23 is stored for each examination part. FIG. 5 shows an example in which the examination site is a breast. The indication marker IM1 is finding information “fat”, the indication marker IM2 is finding information “calcification”, and the indication marker IM3 is finding information “tumor”. Indicates. The finding information here means the finding itself (in a narrow sense) found in the medical image among the information described in the finding column. The medical image server 2 in which the definition information data 23 is stored is an example of an embodiment of a storage unit in the present invention.

  As the modality 3, for example, a nuclear medicine diagnostic apparatus, an X-ray CT (Computed Tomography) apparatus, an MRI (Magnetic Resonance Imaging) apparatus, a general X-ray imaging apparatus, and the like are connected to the network 4.

  Now, creation of an interpretation report in the medical information system 100 will be described with reference to the flowchart of FIG. First, in step S <b> 1, the interpreting doctor inputs information for specifying the interpretation report creation target in the input unit 11 of the interpretation terminal 1. Specifically, the name, examination date, and examination modality of the patient for whom an interpretation report is to be created are entered. In this example, mammography is input as the inspection modality. Incidentally, the image interpretation doctor is an example of the operator in the present invention.

  Next, in step S2, the image interpretation terminal 1 acquires medical image data of an examination corresponding to the information input in step S1 among the medical image data stored in the medical image server 2, and the memory 15 To remember. Further, the image interpretation terminal 1 acquires the patient information and examination information of the examination input in the step S 1 from the patient / examination information data 22 and stores them in the memory 15. Further, the image interpretation terminal 1 acquires definition information data corresponding to the corresponding examination site from the definition information data 23 based on the information on the examination site included in the examination information, and stores the definition information data in the memory 15. To do. In this example, it is assumed that the examination site is the breast.

  Next, in step S3, the image interpretation doctor interprets the medical image displayed on the monitor 13, and sets the instruction marker IM to the medical image in which the finding is recognized. More specifically, the image display control unit 1211 causes the monitor 13 to display a medical image G based on the medical image data stored in the memory 15 as shown in FIG. Further, the image display control unit 1211 displays the indication marker IM stored in the definition information data on the monitor 13.

  The interpretation doctor interprets the displayed medical image G. Then, when a finding to be described in the interpretation report is recognized, an instruction marker IM is set at a corresponding portion of the medical image G.

  The setting of the instruction marker IM will be described. On the monitor 13, an instruction marker IM having a different display form is displayed. The operator selects an instruction marker IM corresponding to the finding recognized in the medical image G from the instruction marker IM, and sets this to the medical image G. More specifically, it is assumed here that a portion that appears to be calcified is recognized in the medical image G whose examination site is the breast. The interpretation doctor uses the mouse of the input unit 11 or the like to place the cursor C on the instruction marker IM2 indicating calcification as shown in FIG. Then, as shown in FIG. 9, a drag and drop operation is performed to set an instruction marker IM <b> 2 in a portion that appears to be calcified in the medical image G.

  As shown in FIG. 10, the indication marker IM is displayed on the medical image G by a right-click operation of the mouse, and the indication marker IM corresponding to the finding is selected from the displayed indication markers IM. You may make it perform setting of IM. In this case, the drag-and-drop operation is not required, and the mouse movement operation can be reduced, so that the troublesome operation of the mouse can be reduced.

  Moreover, as shown in FIG. 11, the diameter of the circumferential portion cf of the indication marker IM may be changed. Thereby, the indication marker IM having a diameter corresponding to the size of the part where the finding is seen can be set.

  When the instruction marker IM2 is set in step S3, in step S4, the interpretation report creating unit 1212 creates an interpretation report in which the finding information indicated by the instruction marker IM2 is described in the finding column. Specifically, the interpretation report creation unit 1212 describes the finding information (calcification) indicated by the instruction marker IM2 set in the medical image G based on the definition information data 23 stored in the memory 15. An interpretation report is created by superimposing the observation field X on the medical image G as shown in FIG. Incidentally, the medical image G here refers to an image of a portion surrounded by a rectangular frame Fr on which an image of the subject is displayed.

  The interpretation doctor may input other information other than the automatically displayed information into the finding column X in characters.

  Incidentally, the interpretation report creation unit 1212 uses the DICOM header information stored in the memory 15, patient information, etc. as information specified by setting the instruction marker IM2, such as series information, image number, and modality information. It may be described in the finding column X based on the inspection information data 22. In addition, the interpretation report creation unit 1212 has a blank space separately from the finding column X as shown in FIG. 13 so that the interpretation doctor can input the diagnostic contents using the keyboard of the input unit 11 or the like. The diagnosis column Y may be superimposed on the medical image G.

  The interpretation report created in step S4, that is, the interpretation report having the finding column X and the diagnosis column Y on the medical image G is stored in the medical image server 2.

  According to this example, since the contents of the finding column X are created semi-automatically only by setting the instruction marker IM in the medical image G, the interpretation doctor can create an interpretation report more easily than before. it can.

  Next, a modification of the first embodiment will be described. First, the first modification will be described. In this example, as the definition information data 23, as shown in FIG. 14, a plurality of types of the indication markers IM1, IM2, IM3,. Information (diagnosis information) of the contents of the diagnosis column indicated by the instruction marker IM is stored. When the instruction marker IM is set in step S3, the interpretation report creating unit 1212 indicates the instruction marker IM set in the medical image G based on the definition information data 23 in step S4. An interpretation report is created by superimposing the diagnostic column Y in which the diagnostic information is written on the medical image G (not shown). Further, the interpretation report creating unit 1212 may superimpose a blank finding field X on the medical image G. In this case, the interpretation doctor writes the findings in text in the finding field X.

  Next, a second modification will be described. Once the examination site and findings are identified, the diagnosis content is narrowed down. Accordingly, diagnostic information conceivable from the examination site and the findings is stored in advance in the medical image server 2, and when the instruction marker IM is selected according to the findings in step S3, the interpretation report creating unit 1212 You may make it display the candidate of diagnostic information based on the kind of said indication marker IM, and the test | inspection site | part contained in the test | inspection information acquired in step S2.

(Second embodiment)
Next, a second embodiment will be described. However, items different from the first embodiment will be described.

  A medical information system 100 ′ of this example shown in FIG. 15 is connected to the image interpretation terminal 1, the medical image server 2 and the modality 3 through the network 4 in addition to the image interpretation terminal 1 ′, the medical image server 2 and the modality 3. The image interpretation report server 5 is provided. Although not specifically shown, the interpretation report server 5 has the same data as the patient / examination information data 22 stored in the medical image server 2 (patient name, patient ID, examination date, examination modality, examination Information such as a part) is stored.

  As shown in FIG. 16, the CPU 12 in the interpretation terminal 1 ′ has an image viewer 121 ′, an interpretation report creation unit 122, a measurement unit 123, and a position specification unit 124. Therefore, unlike the first embodiment, in this example, the function of the image viewer and the function of creating an interpretation report are separate.

  The image viewer 121 ′ executes a function of displaying an image on the monitor 13, and displays the medical image G taken by the modality 3 and the instruction marker IM on the monitor 13. The interpretation report creation unit 122 executes a interpretation report creation function. In this example, unlike the first embodiment, an interpretation report is created on a different screen from the medical image. Details will be described later. The interpretation report creation unit 122 is an example of an embodiment of an interpretation report creation unit in the present invention.

  The measurement unit 123 measures the size of the part indicated by the indication marker IM. Details will be described later. The measurement unit 123 is an example of an embodiment of the measurement unit in the present invention.

  The position specifying unit 124 specifies the set position of the instruction marker IM set in the medical image G. Details will be described later. The position specifying unit 124 is an example of an embodiment of the position specifying unit in the present invention.

  Creation of an interpretation report in this example will be described. In this example, an example of creating an interpretation report for a head CT image will be described. Also in this example, an interpretation report is created in the same manner as in the flowchart of FIG. However, in this example, since the examination site is the head, in step S2, definition information data of the head (a specific example is not shown) is acquired.

  In step S2, the interpretation terminal 1 ′ acquires the patient / examination information data stored in the interpretation report server 5 instead of the patient / examination information data 22 stored in the medical image server 2, and Store in the memory 15.

  In step S3, in addition to the medical image G, an interpretation report creation screen GR is displayed on the monitor 13 as shown in FIG. The interpretation report creation unit 122 displays the interpretation report creation screen GR. The interpretation report creation screen GR may be displayed on a monitor different from the medical image G.

  In the interpretation report creation screen GR, X11 is a column for displaying patient information such as patient name and ID, information such as imaging modality, and imaging date, X12 is a finding column for entering findings, and X13 is for entering diagnostic details. This is a diagnostic column. X14 is a field in which a screen for selecting patient information such as a patient's name, height, weight, blood type, imaging information such as an imaging region, and past interpretation reports is displayed. Furthermore, the interpretation report creation screen GR may further include an image field to which an image serving as a key in diagnosis is attached.

  The interpretation report creation unit 122 is configured to obtain patient information such as patient name and ID in the column of X11 and information such as examination modality and examination date based on the patient / examination information data acquired from the interpretation report server 5. Display.

  When the medical image G and the interpretation report creation screen GR are displayed, the interpretation doctor performs interpretation as in the first embodiment, and if the findings to be described in the interpretation report are recognized, the medical image is displayed. The instruction marker IM is set at a corresponding position of G.

  In this example, it is assumed that hematoma is observed as a finding. In step S3, the interpretation doctor selects an instruction marker IM1 indicating hematoma and sets it to the medical image G. At this time, the size of the hematoma is measured by setting the instruction marker IM1. Specifically, the interpreting physician aligns the indication marker IM1 with the portion where the finding is recognized, and adjusts the diameter of the circumferential portion cf of the indication marker IM so that the circumferential portion cf is positioned on the outer edge of the hematoma. To set the indication marker IM1. When the instruction marker IM1 is set, the measurement unit 123 measures the diameter of the circumferential portion cf.

  In addition, when the instruction marker IM1 is set, the position specifying unit 124 specifies the setting position of the instruction marker IM1 in the medical image G, and specifies the position of the part instructed by the instruction marker IM1 in the subject. To do. For example, when the pointing marker IM1 is set at the position shown in FIG. 18 in the medical image G that is a head CT image, the position specifying unit 124 detects the outline of the head on the image, The setting position of the instruction marker IM1 in the image G is specified, and the setting position of the instruction marker IM1 is specified to be the right head using the position specifying information and the information on the examination site.

  In step S4, the interpretation report is created separately from the medical image. Specifically, when the instruction marker IM1 is set in the step S3, in the step S4, the interpretation report creation unit 122 is specified by the finding information indicated by the instruction marker IM1 and other settings of the instruction marker IM1. The image interpretation report described in the finding column X12 is created. In this example, the interpretation report creating unit 122 interprets in the observation column X12, for example, that “a 2 cm large hematoma is seen on the right side of the head CT image of series 2, image number 10”. Create

  The information of “series 2, image number 10” is based on the DICOM header information of the medical image G in which the instruction marker IM1 is set. The “head CT image” information is based on the patient / examination information data 22 of the medical image G in which the instruction marker IM1 is set. The information on the “right head” is based on the position information of the pointing marker IM1 specified by the position specifying unit 124. The information “2 cm large” is based on information on the diameter of the circumferential portion cf measured by the measurement unit 123. The information of “hematoma” is based on the definition information data 23. These pieces of information are all specified by the setting of the instruction marker IM1.

  In this example, the interpretation report created in step S4 is stored in the interpretation report server 5.

  According to this example, as in the first embodiment, the contents of the finding column X12 are created semi-automatically only by setting the instruction marker IM in the medical image G. Can be created more easily.

  As mentioned above, although this invention was demonstrated by said each embodiment, of course, this invention can be variously implemented in the range which does not change the main point. For example, in the above-described embodiment, the information specified by the setting of the instruction marker IM and described as the content of at least one of the observation column and the diagnosis column in the interpretation report is an example, and is not limited to the above. Absent.

  In the second embodiment, the definition information data 23 may be stored in the interpretation report server 5.
