## Abstract

A radiation tomography apparatus comprising a first imaging device for taking tomography images of a subject by introducing the subject in an introduction direction of the subject, a support member for supporting the subject, a support-member moving device for moving the support member in the introduction direction of the subject, a support-member movement controller for controlling the support-member moving device, a first cylinder provided in a first imaging view field of the first imaging device and having an opening extending in the introduction direction for introducing the support member and a first positioning device for positioning the first cylinder relative to the first imaging view field, the first cylinder guiding the movable support member.

## Claims

### Claim 1

A radiation tomography apparatus comprising:
a first imaging device for taking tomography images of a subject by introducing the subject in an introduction direction of the subject;
a support member for supporting the subject;
a support-member moving device for moving the support member in the introduction direction of the subject;
a support-member movement controller for controlling the support-member moving device;
a first cylinder provided in a first imaging view field of the first imaging device and having an opening extending in the introduction direction for introducing the support member; and
a first positioning device for positioning the first cylinder relative to the first imaging view field,
the first cylinder guiding the movable support member.

### Claim 2 (depends on 1)

The radiation tomography apparatus according to claim 1, further comprising:
a second imaging device provided adjacent to the first imaging device in the introduction direction for taking tomography images of the subject by introducing the subject in the introduction direction;
a second cylinder provided in a second imaging view field the second imaging device and having an opening extending in the introduction direction for introducing the support member; and
a second positioning device for positioning the second cylinder relative to the second imaging view field,
the second cylinder guiding the movable support member.

### Claim 3 (depends on 1)

The radiation tomography apparatus according to claim 1, wherein
a position of the cylinder relative to the imaging view field is adjusted by a jig.
