在に支承したことを特徴とする多軌道断層撮影装置。The X-ray tube and the film are moved relative to each other at least in a straight line or in a circular orbit across the object, and a grid for removing scattered radiation arranged on the film is subjected to a linear rocking motion or a heliotropic rotation motion. In the apparatus for photographing the subject, a swing drive source is provided on a grid holding mechanism board that moves relative to the X-ray tube for a predetermined distance in a direction perpendicular to the radiation off-axis direction of the X-ray tube. A swinging member is provided, and a grid rotating member is rotatably supported on this member by guide rollers, the grid rotating member being configured to rotate the grid around the radial off-axis as a center of rotation. A multi-orbital tomography device.
