Radiographic X-ray device

A radiographic X-ray device comprising:

• an X-ray imaging system 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 system using a coordinate system having a mechanical center of the device as a reference point;
• a shape data registering means of the X-ray imaging system for registering external shape data of three dimensional models corresponding to three dimensional shapes of objects;
• a positional relation detecting means for obtaining in real time information regarding positional relations of the X-ray imaging system based on a current position of the X-ray imaging system and external shape data of a 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 system detected by the positional relation detecting means.

• and
• a top board for carrying a subject being inspected, said top board configured to move in reference to the common coordinate system of the X-ray imaging system having the mechanical center of the device as the reference point,
• wherein said shape data registering means registers shapes of three dimensional models corresponding to the top plate's external shape;
• and said positional relation detecting means obtains the information regarding positional relations between the X-ray imaging systems and the top plate based on their current positions and the external shape data of the three dimensional model so that the imaging system transport control means can control the X-ray imaging system transport mechanism in accordance with the information regarding the positional relation between the top plate and the X-ray imaging system.
