Abstract
One purpose of this invention is to provide radiation tomography apparatus with easier maintenance. A specific approach for this purpose is as follows. That is, a detector ring in the radiation tomography apparatus includes two or more rings. Moreover, a ring moves as to approach a next ring, whereby both the rings are connected. If radiation tomography is conducted while a clearance is provided between the rings, detection sensitivity of the detector ring decreases due to the clearance. On the other hand, according to this invention, the ring moves as to approach the next ring, which results in a narrower clearance. Accordingly, radiation that is not observed may be reduced as much as possible.
