Abstract
A tomographic apparatus includes a movable radiation generating system and a movable radiation sensing system which may be placed independently of the location of the radiation generating system. The locus of movement of a radiation generating point is adjusted to be parallel to the arrangement of the radiation sensing system. The distance between the generating and sensing systems is obtained by a prescribed calculation. The CT scanning starts after initializing the radiation generating/sensing systems. Then, projecting data of the inspection object is obtained. Thereafter, image reconstruction processing is performed onto the obtained projection data in accordance with a sequential approximation method, so that a tomographic image of the object is produced. According to the above tomographic apparatus, since the movable radiation sensing system is independent of and optionally separated from the movable radiation generating system, it is possible to obtain the tomographic image of a large object, even if such an object cannot be moved and/or any obstructions exist around the object.
