Subject information such as D, name, gender, date of birth, etc. is input from the operation unit 53 by the operator while viewing the input screen displayed on the monitor 54, and is stored in the memory of the system control unit 52 (step). 1). If multiple subjects are scheduled to be photographed on the day, information on all scheduled subjects may be entered in advance. In this case, the previous subject's photographing is completed. When the operation is performed, the subject information of the next subject is displayed on the monitor 54.

When the previous subject's imaging is completed and the subject information of the next subject is displayed on the monitor 54, or when the subject information of a new subject is input and the content is confirmed, the step 2, the operator performs a subject information input confirmation operation by the operation unit 53 and continues to input an examination plan and the like. In response to the subject information input confirmation operation, the name of the subject P is extracted from the patient information previously input from the operation unit 53 and stored in the memory of the system control unit 52. The name of the examiner P is displayed on the display device 6 provided on the surface of the gantry 2 of the X-ray CT apparatus (step 3). Further, a medical staff such as an operator calls a new subject P waiting in the waiting room into the examination room 1 and the called subject P enters the examination room 1 (step 4).

Thus, when the subject P enters the examination room 1, first, the subject P sees his / her name displayed on the display device 6 provided on the surface of the gantry 2 of the X-ray CT apparatus. Therefore, it is possible to confirm the person's name displayed on the display device 6 by himself and recognize that the person undergoing the inspection is himself.

(Step 12). At this time, the medical image displayed on the X-ray film and the medical image displayed on the monitor are subject to the subject such as the name of the subject P and the subject ID based on a series of control routines by the system control unit 52. The examiner information is also displayed. The same subject information is also displayed on the generated report.

Thus, since the subject information input to the system control unit 52 is extracted and the name of the subject is displayed on the display device 6 as an imaging routine in the X-ray CT apparatus, the subject name is displayed. When P can enter the examination room 1 by himself / herself, the examinee P himself / herself confirms the name displayed on the display device 6 so that the examinee does not mix up. In the unlikely event that the name displayed on the display device 6 is not your name, you can report it to the medical staff.
The mistake is promptly corrected. In addition, when the subject is placed on a stretcher and carried to the examination room 1, the accompanying medical staff or attendant confirms the name displayed on the display device 6, It is possible to prevent the subject from being mistaken.

In addition, the name of the subject P, the subject ID, etc., which are input as an imaging routine, are also included in the medical image displayed on the X-ray film, the medical image displayed on the monitor, and the report indicating the interpretation result. Since the subject information is displayed, the subject P and the interpretation result can be matched even after the examination.
