PROBLEM TO BE SOLVED: To provide a radiation tomography apparatus capable of acquiring clear tomographic images without shaking a subject M even when a rail is not arranged inside an imaging visual field.SOLUTION: A radiation tomography apparatus includes a support member 2 for supporting a subject M, and a rail L1 for mounting the support member 2. The support member 2 is moved on the rail. Then, when the subject M is moved to a position to be introduced to an imaging visual field of a first imaging part C1, a wheel 2a is projected from an end of the rail L1. Then, when the subject M is moved further, the wheel 2a is then abutted to an auxiliary rail L2. When configured in such a manner, the need of providing the rail in the entire movable range of the wheel 2a is eliminated. Thus, the support member 2 is surely supported on the rail L1 and the auxiliary rail L2 by wheels 2a and 2b regardless of the movement, diversity of the position of the subject M is not caused during imaging, and tomographic images with high visibility are provided. |
