When X-ray tube direction of 21 and x-ray detector 22 (direction of lighting direction and the detection aspect) it is fixed in, by the fact that in one for X-ray tube 21 and the one for x-ray detector 22 two it has, to do x-ray perspective photographing from various directions it is possible the carriage rail of the U letter die raceway which consists of the raceway of two rectilinear conditions which are laid out mutually in opposition and the raceway of the curved line condition which is jointed to those. In addition, when the plane view doing, carriage rail by the fact that lays out the carriage rail 41 of the U letter die raceway for 31 of the U letter die raceway for X-ray tube 21 and x-ray detector 22 mutually in opposition, it can take the direction of x-ray perspective mainly.X線管21やX線検出器22の向き(照射方向や検出面の向き)が固定されている場合において、互いに対向に配置された2つの直線状の軌道およびそれらに接続された曲線状の軌道からなるU字型軌道のレールをX線管21用およびX線検出器22用に2つ備えることで、様々な方向からX線透視撮影を行うことができる。また、平面視したときにX線管21用のU字型軌道のレール31およびX線検出器22用のU字型軌道のレール41を互いに対向に配置することで、X線透視の方向を多くとることができる。
