  The CPU 80pr provided in the client terminal 80 for the image technician performs processing according to the flowcharts shown in FIGS. It should be noted that a control program (image detection support program) corresponding to these flowcharts is stored in the HDD 80hd.

  Referring to FIG. 11, in step S1, the basic screen is developed in main monitor area 801 of DRAM 80 mm. The developed basic screen is read by the main monitor 80mt1 and displayed as shown in FIG. Referring to FIG. 5, the basic screen has a heading display field IDX1 arranged in the upper stage and an image display field IMG1 arranged in the lower stage.

  Among these, the headline display column IDX1 displays headings of a plurality of examination image lists each including file information, patient information, examination codes, and the like. In the image display field IMG1, a plurality of headline images are displayed side by side. The plurality of displayed headline images respectively correspond to the plurality of medical images obtained by the examination indicated by the desired headline on the headline display field IDX1. Note that when the step S1 is executed, the image display field IMG1 is blank.

  Returning to FIG. 11, it is determined in step S3 whether or not a headline selection operation (= an operation for clicking a desired headline on the headline display column IDX1) has been performed by the keyboard / mouse 80km. In step S5, the keyboard / mouse 80km is determined. To determine whether another operation has been performed.

  If both the determination result in step S3 and the determination result in step S5 are NO, the process returns to step S3. If the determination result in step S5 is YES, the process proceeds to another process. If the determination result in step S3 is YES, the process returns to step S3. Proceed to step S7.

  In step S7, an inspection image list corresponding to the headline selected by the headline selection operation is specified, and a DICOM file created by the inspection indicated by the specified inspection image list is acquired from the RIS / image detection server 40 through the hospital LAN 100. In step S9, a plurality of heading images respectively corresponding to the plurality of medical images in the acquired DICOM file are created, and the created heading images are developed in the main monitor area 801 of the DRAM 80mm. As a result, a plurality of headline images are displayed in the image display field IMG1.

  In step S11, an imaging screen including a plurality of medical images in the DICOM file acquired in step S7 is developed in the sub monitor area 802 of the DRAM 80 mm. The developed image inspection screen is read by the sub monitor 80mt2 and displayed as shown in FIG. According to FIG. 6, the imaging screen has a plurality of sub-screens arranged in a matrix, and a plurality of medical images are respectively displayed on the plurality of sub-screens.

  However, the position of the tomographic image representing the examination site is deviated from the center position of the medical image depending on the position of the patient at the time of imaging. Similarly, the angle of the tomographic image representing the examination site rotates clockwise or counterclockwise depending on the posture of the patient at the time of imaging. That is, an offset may occur in the position and angle of the tomographic image depending on the position and posture of the patient at the time of imaging.

  Returning to FIG. 11, in step S13, it is determined whether or not a rotation operation has been performed with the keyboard / mouse 80km. If the determination result is NO, the process proceeds directly to step S17. If the determination result is YES, the process proceeds to step S15. After executing the following processing, the process proceeds to step S17.

  In other words, in step S15, a plurality of tomographic images on the imaging screen are collectively rotated to a desired angle, and a plurality of heading images on the image display field IMG1 are simultaneously rotated to a desired angle.

  In step S17, it is determined whether or not a moving operation has been performed using the keyboard / mouse 80km. If the determination result is NO, the process proceeds directly to step S21. If the determination result is YES, the following process is performed in step S19. Then, the process proceeds to step S21.

  That is, in step S19, the plurality of tomographic images displayed on the imaging screen are collectively moved to a desired position, and the plurality of heading images displayed in the image display field IMG1 are collectively moved to the desired position. Move.

  Therefore, when a rotation operation is performed on the imaging screen shown in FIG. 6, a plurality of tomographic images are rotated as shown in FIG. Further, when a moving operation is performed on the imaging screen shown in FIG. 8, the plurality of tomographic images are moved as shown in FIG. Furthermore, as a result of such rotation processing and movement processing being executed, the display of the headline display field IMG1 is updated as shown in FIG.

  Returning to FIG. 12, in step S <b> 21, it is determined whether or not an imaging completion operation has been performed with the keyboard / mouse 80 km. In step S23, it is determined whether or not another operation has been performed with the keyboard / mouse 80km. If both the determination result in step S21 and the determination result in step S23 are NO, the process returns to step S13. If the determination result in step S23 is YES, the process proceeds to another process. If the determination result in step S21 is YES, the process proceeds to step S13. Proceed to step S25.

  In step S25, offset calibration information describing the rotation angle according to the rotation operation and the movement amount according to the movement operation (each movement amount in the horizontal direction and the vertical direction) is created, and the created offset calibration information is acquired in step S7. Append to the DICOM file (see FIG. 3B). The offset calibration information is thus assigned to the medical image to be calibrated.

  When the “image detection complete” button is clicked without performing the rotation operation, the rotation angle described in the offset calibration information indicates “0 °”. Similarly, when the “image completion” button is clicked without performing a movement operation, the movement amount described in the offset calibration information indicates “0 pix” in both the horizontal direction and the vertical direction.

  In step S27, the DICOM file to which the offset calibration information is added is stored in the PACS 70 through the in-hospital LAN 100. When the saving is completed, the process returns to step S3.

  The CPU 90pr provided in the interpretation medical client terminal 90 executes processing according to the flowcharts shown in FIGS. A control program (medical diagnosis support program) corresponding to these flowcharts is stored in the HDD 90hd.

  Referring to FIG. 17, in step S31, a basic screen is developed in main monitor area 901 formed in DRAM 90mm. The developed basic screen is read by the main monitor 90mt1 and displayed as shown in FIG.

  According to FIG. 13, the basic screen has a heading display column IDX2 in which a plurality of headings each representing a plurality of inspection image lists are listed. In addition, on the basic screen shown in FIG. 13, the interpretation report corresponding to any column is set to “pending”.

  In step S33, it is determined whether or not a headline selection operation (= operation for selecting a desired headline on the headline display column IDX2) has been performed with the keyboard / mouse 90km. In step S35, it is determined whether or not another operation has been performed with the keyboard / mouse 90km.

  If both the determination result in step S33 and the determination result in step S35 are NO, the process returns to step S33. If the determination result in step S35 is YES, the process proceeds to another process, and if the determination result in step S33 is YES. Proceed to step S37.

  In step S37, an interpretation report screen corresponding to the headline selected by the headline selection operation is developed in the main monitor area 901 formed in the DRAM 90mm. The basic screen on the main monitor area 901 is updated by the interpretation report screen.

  The updated interpretation report screen is read by the main monitor 90mt1 and displayed in the manner shown in FIG. According to FIG. 14, the interpretation report screen is provided with a finding field RMK, a diagnosis field DGN, a request comment field REQ, and an attached image field IMG. Among these, a character string written by the attending physician is displayed in the request comment field REQ.

  In step S39, the inspection image list corresponding to the headline selected by the headline selection operation is specified, and the DICOM file created by the inspection indicated by the specified inspection image list is acquired from the PACS 70 through the hospital LAN 100.

  In step S41, an interpretation screen including a plurality of medical images in the acquired DICOM file is developed in the sub-monitor area 902 formed in the DRAM 90mm. In step S43, ROI information (support information) is created by measuring pixel values of medical images constituting the expanded interpretation screen. Here, the ROI information includes a circle surrounding the region of interest (a part of the guide image), a lead line drawn from the circle (the other part of the guide image), and the measurement results of a plurality of pixel values belonging to the region of interest. And a character string (other part of the guide image).

  In step S45, the created ROI information is multiplexed on the interpretation screen on the sub monitor area 902. The image interpretation screen and the ROI information developed in this way are read out by the sub monitor 90mt2 and displayed as shown in FIG.

  In step S47, offset calibration information is extracted from the DICOM file acquired in step S39. In step S49, it is determined whether or not the rotation angle or the movement amount described in the extracted offset calibration information indicates a significant value (a value different from = 0). If the determination result is NO, the process directly proceeds to step S55. On the other hand, if the determination result is YES, the following process is executed in steps S51 and S53, and then the process proceeds to step S55.

  That is, in step S51, a plurality of medical images constituting the image interpretation screen developed in step S41 are calibrated at once according to the offset calibration information. The tomographic image that appears in each medical image is rotated according to the rotation angle described in the offset calibration information, and is moved according to the movement amount described in the offset calibration information.

  In step S53, the circle, the lead line, and the character string constituting the ROI information multiplexed in step S45 are calibrated according to the offset calibration information. At this time, the positions of the circle, the leader line, and the character string are changed according to the rotation angle and the movement amount described in the offset calibration information. However, the angles of the circle, the leader line, and the character string are maintained at the original angles regardless of the rotation angle described in the offset calibration information.

  In step S55, it is determined whether or not a finding / diagnosis input operation has been performed using the keyboard / mouse 90km. If the determination result is NO, the process proceeds directly to step S59. If the determination result is YES, the following is performed in step S57. After executing the processing, the process proceeds to step S59.

  That is, in step S57, a desired character string is drawn in the finding column RMK or the diagnostic column DGN on the interpretation report screen developed in the main monitor area 901 of the DRAM 90mm. The drawn character string is reflected on the display of the main monitor 90mt1 in the manner shown in FIG.

  In step S59, it is determined whether an image attachment operation (= drag and drop operation for a desired medical image on the sub monitor 90mt2) has been performed with the keyboard / mouse 90km. If the determination result is NO, the process proceeds directly to step S65. On the other hand, if the determination result is YES, the following processing is executed in steps S61 and S63, and then the process proceeds to step S65.

  That is, in step S61, a thumbnail image corresponding to a desired medical image is created. In step S63, the created thumbnail image is multiplexed in the attached image column IMG on the interpretation report screen developed in the main monitor area 901. The multiplexed thumbnail images are reflected on the display of the main monitor 90mt1 in the manner shown in FIG.

  In step S65, it is determined whether or not the “OK” button on the interpretation report screen has been clicked with the keyboard / mouse 90 km. In step S67, it is determined whether or not another operation has been performed with the keyboard / mouse 90km.

  If both the determination result in step S65 and the determination result in step S67 are NO, the process returns to step S55. If the determination result in step S67 is YES, the process proceeds to another process, and the determination result in step S65 is YES. For example, after the confirmation process is performed in step S69, the process returns to step S31.

  As can be seen from the above description, the medical diagnosis support system performs the diagnosis for the medical image that has undergone the imaging operation and the client terminal 80 that supports the imaging operation for the medical image output from the modality 60. And a client terminal 90 to be supported.

  When the image inspection operation is completed, the CPU 80pr provided in the client terminal 80 adds offset calibration information to the DICOM file containing the medical image (S25), and then stores the DICOM file in the PACS 70 (S27). Thereby, offset calibration information is assigned to the medical image.

  The CPU 90pr provided in the client terminal 90 acquires a DICOM file from the PACS 70 (S39), measures the pixel value of the medical image stored in the acquired DICOM file, and creates ROI information (S43). The CPU 90pr also calibrates the medical image in the acquired DICOM file according to the offset calibration information in the same DICOM file, and displays the calibrated medical image on the sub monitor 90mt2 (S41, S51). The ROI information is multiplexed on the displayed medical image (S45, S53).

  Thus, the ROI information is created by measuring the pixel value of the medical image before the offset calibration is performed, and is displayed in association with the display of the medical image after the offset calibration is performed. As a result, it is possible to reduce a concern that a pixel value shift caused by the offset calibration is reflected in the ROI information and an accurate image diagnosis of the doctor is hindered.

  In this embodiment, when a rotation operation or a movement operation is performed in a state where the image detection screen is displayed, a plurality of tomographic images on the image detection screen are rotated or moved together. However, the plurality of tomographic images may be individually rotated or moved. In this case, an operation for selecting a desired tomographic image is necessary prior to the rotation operation or the movement operation.
