  In the above description, a case where an image interpretation person with an interpretation person ID “B-01” who is permitted to interpret image data to which an examination person ID “A-01” is added interprets the image data. As described above, a radiographer such as the radiographer ID “B-02” or the radiographer ID “B-03” whose radiogram interpretation is not permitted (that is, the access right is not set) When performing interpretation of the image data, the output permission determination unit 43 performs output permission determination that permits output of only the image data, or performs output permission determination that does not permit output for any of the image data and patient information. An output propriety signal generated based on these output propriety determinations is supplied to the control unit 34 of the image interpretation apparatus 3 (step S7 in FIG. 8).

  When the output of only the image data is permitted, the control unit 34 supplies only the image data stored in the data storage unit 31 to the output unit 35 for display (step S10 in FIG. 8). When neither output of image data nor patient information is permitted, the control unit 34 refuses supply of the image data to the output unit 35 and inputs a word indicating that image interpretation is impossible as necessary. Are displayed on the display panel or the monitor 353 of the output unit 35 (step S11 in FIG. 8).

  On the other hand, when the print output format is selected in the selection of the output format in the above-described step S6, the output permission determination unit 43, like the display output format, checks the examiner ID, the radiographer ID, and the access right. Checking whether to allow output of image data and patient information, collating data, determining whether to allow output of only image data, determining whether to allow output of only image data, and determining whether to permit output of either image data or patient information Then, an output propriety signal generated based on these output propriety determinations is supplied to the control unit 34 of the image interpretation apparatus 3 (step S7 in FIG. 8).

  At this time, the control unit 34 that has received the output permission signal permitting the output of the image data and the patient information reads the image data and the patient information stored in the data storage unit 31 and supplies them to the printing unit 355 of the output unit 35. Then, the print data generation unit 356 generates print data in a predetermined format using the above-described image data and patient information, and performs film printing by the film printer 357 (step S8 in FIG. 8).

  On the other hand, when the output of only the image data is permitted, the control unit 34 supplies only the image data stored in the data storage unit 31 to the printing unit 355 of the output unit 35 to perform film printing (see FIG. In step S10 of FIG. 8, if neither output of image data nor patient information is permitted, the control unit 34 refuses to supply the image data to the output unit 35 and indicates that printing is not possible as necessary. Is displayed on the display panel of the input unit 33 (step S11 in FIG. 8).

  According to the embodiment of the present invention described above, based on the identification information of the inspection person in charge of the inspection facility and the interpretation person in charge of the interpretation facility, and the medical information access right preset between these persons in charge, the image data and the patient Since the output of information and the like is controlled, it is possible to prevent the personal information of the examinee from leaking to other medical staff not related to the interpretation of the image data.

  In addition, according to the present embodiment, work such as masking processing on the image data is not required, so that the burden on the inspector is reduced, and furthermore, the original image data and the processed image data are not mixed in the interpretation network. Troubles such as image data mix-up can be prevented.

  Furthermore, in the above-described embodiment, since the access right management device and the image interpretation device are installed in an independent facility, it becomes possible to strictly perform security management for the personal information of the examinee.
