ABSTRACT:
An optical camera for photographing a subject held on a rotary stage is disposed on the rotation axis of the rotary stage. A computer calculates a region where CT imaging is possible around the rotation axis by using information relating to the positional relation of an X-ray source, an X-ray detector and the rotary stage in the direction of the optical axis of an X-ray, and information relating to the size of a light receiving surface of the X-ray detector. The region where CT imaging is possible is displayed being superimposed with a subject image photographed by the optical camera on an displaying unit, whereby the position of the subject at that time point can be easily compared with the region where the X-ray transmission data can be obtained.
