  If the medium 50 read by the media drive 48 has no numerical report information and only medical image data is stored, the box D1 of the normal interpretation screen 431 and the box D2 of the alerting interpretation screen 432 are not displayed.

  When there are a plurality of numerical report objects on the medium 50 read by the media drive 48, a plurality of boxes D1 on the normal interpretation screen 431 and a plurality of boxes D2 on the warning interpretation screen 432 are displayed.

  In this case, if there is no numerical report information object having a numerical abnormality, the normal interpretation screen 431 is displayed, and if there is even one numerical report information object having a numerical abnormality, a warning interpretation screen 432 is displayed. Further, on the warning interpretation screen 432, only the box D2 corresponding to the number report information object having a numerical abnormality is opened and displayed from the beginning.

[Operation of medical imaging system]
Next, the operation in the medical image system 100 will be described. FIG. 12 is a ladder chart showing processing executed in the modality 20, the PACS 30, and the image interpretation terminal 40.

  As shown in FIG. 12, the modality 20 images a patient (Step S1) and generates medical image data (Step S2). The modality 20 transmits the medical image data generated in step S2 to the PACS 30 (step S3). The PACS 30 stores the medical image data transmitted from the modality 20 (step S4).

  The user performs a media writing operation and designates medical image data to be written on the media 50. Then, the PACS 30 selects medical image data to be written on the medium 50 based on the operation signal from the operation unit 32 based on the medium writing operation (step S5). Then, the PACS 30 performs automatic measurement processing on the image data included in the selected medical image data (Step S6), and generates numerical report information (Step S7). At this time, the medical image data and the numerical report information are associated based on the incidental information.

  Then, the PACS 30 writes the selected medical image data and the generated numerical report information on the medium 50 (step S8).

  The user takes out the medium 50 on which the medical image data and the numerical report information are written from the media drive 38 of the PACS 30 and stores it in the media drive 48 of the image interpretation terminal 40.

  When the medium 50 is stored in the media drive 48 of the image interpretation terminal 40, the image interpretation terminal 40 reads medical image data and numerical report information from the medium 50 (step S9).

  Then, the interpretation terminal 40 performs an interpretation screen display process based on the read medical image data and numerical report information (step S10).

  FIG. 13 is a flowchart showing an interpretation screen display process performed by the interpretation terminal 40. As shown in FIG. 13, the interpretation terminal 40 analyzes the numerical report information read from the medium 50 (step S101). Then, with reference to the numerical report abnormal value table 461, it is determined whether or not the item “value” in the numerical report actual data is an abnormal value (step S102).

  As a result of the determination, if it is not an abnormal value (step S102; No), the interpretation terminal 40 displays the normal interpretation screen 431 based on the medical image data and the numerical report information (step S103). Moreover, when it is an abnormal value as a result of determination (step S102; Yes), the interpretation terminal 40 displays the warning interpretation screen 432 based on medical image data and numerical report information (step S104).

  As described above, according to the present embodiment, regardless of the purpose of interpretation by the interpreting physician, the PACS 30 determines the examination type of the automatic measurement process based on the incidental information of the medical image data, and performs the automatic measurement process of the decided examination type. To generate numerical report information. Then, when the value of the generated numerical report information is an abnormal value, the interpretation terminal 40 displays a warning to that effect (a warning interpretation screen 432).

  Therefore, it is possible to prevent oversight of diseases that are not intended for interpretation by the interpreting physician (not intended for examination). Specifically, it is possible to prevent an abnormality in the cardiothoracic ratio from being overlooked even when the medical image of the chest imaged by the CR device is interpreted for purposes other than the purpose of examining the cardiothoracic ratio for the prevention of heart failure.

  Furthermore, since the numerical report information and the medical image data are associated with each other, the interpretation doctor can specify a medical image indicating an abnormal value.

  Further, since the examination numerical report other than the interpretation purpose is displayed as an annotation separately from the image without being superimposed on the image data, the examination numerical report other than the interpretation purpose is not displayed on the medical image. Therefore, the interpretation of the medical image by the interpretation doctor is not hindered.

  Further, since medical image data and numerical report information are transferred offline from the PACS 30 to the interpretation terminal 40 using the medium 50, even if a trouble such as a network disconnection occurs, the medical image and the inspection numerical value other than the interpretation purpose are used. Reports can be provided easily.

  In the present embodiment, the image interpretation terminal 40 may be included in a medical image system different from the medical image system 100. For example, the interpretation terminal 40 may be in a medical facility (hospital B) different from the medical facility (hospital A) including the RIS 10, the modality 20, and the PACS 30.

  In the present embodiment, the modality 20 has an automatic measurement type table 361, a media drive 38, and a function for generating numerical report information, and the modality 20 writes medical image data and numerical report information to the medium 50. It is good also as a structure.

  Further, an automatic measurement type table 361, a media drive 38, and a function for generating numerical report information are provided in a device different from the modality 20 and the PACS 30, and the separate device has the medical image data and the numerical report. The information may be written on the medium 50.
