By inputting information identifying the department name or patient case with a touch panel that displays a PAS switch for setting imaging conditions on the console panel and the console input device, the department name or patient case can be displayed. Corresponding 1
Alternatively, a means for reading out a plurality of shooting conditions from the storage unit and displaying only the PAS switch of the read shooting conditions on the panel is provided.

[0006]

In the CT apparatus of the above means, for example, when the operator inputs his / her ID number or the case of the patient with the input device of the console, the computer discriminates the operator and corresponds to the case of the operator or the patient. The necessary minimum PAS switches stored in the storage unit are displayed on the touch panel. Then, when the PAS switch displayed on the touch panel is selected with a single touch, shooting is started under the shooting conditions set on the PAS switch, and a tomographic image is displayed on a predetermined monitor. For this reason, the operator can quickly select the PAS switch of the imaging condition to be executed without erroneously recognizing it.
