Abstract:
1. A radiographic X-ray device comprising: a plurality of X-ray imaging systems each comprising an X-ray tube for radiating X-rays and an X-ray detector for detecting transmitted X-rays, which are arranged to face each other and are mounted on each end of a support arm; an X-ray imaging system transport mechanism for transporting the X-ray imaging systems using a common coordinate system having a mechanical center of the device as a reference point; a shape data registering means for each X-ray imaging system for pre-registering three dimensional external shape data models corresponding to three dimensional external shape data models of the X-ray imaging system, wherein the models are in a voxel data tree format; a positional relation detecting means for obtaining in real time information regarding positional relations of the X-ray imaging systems based on a current position of each X-ray imaging system and the external shape data of the three dimensional model; and an imaging system transport control means for controlling the X-ray imaging system transport mechanism in accordance with the information regarding the positional relations of the X-ray imaging systems detected by the positional relation detecting means.
