Abstract

A radiation imaging apparatus avoids collisions of the radiation with an obstacle, and includes a flat panel detector (FPD) connected with a supporting axis facing a vertical direction to a ray detection surface. A supporting axis is supported rotatably due to the action of the bearing and the flat panel detector rotates around the supporting axis as the center of the rotation via the supporting axis by driving with the motor. A frame member surrounding the flat panel detector has a circular outer appearance of which a center is the supporting axis, and the diameter of the frame member is longer than the length of the diagonal line of the flat panel detector.

Dependent claims

A radiation imaging apparatus, comprising:

a radiation detector;
an arm that supports said radiation detector;
a rotation mechanism that rotates said radiation detector around an axis facing a vertical direction to a radiation detection surface relative to said arm;
wherein a frame member that has a circular form, which has a center aligned with said axis, and further includes an outer shape surrounding said radiation detector and is installed relative to a circumference of a radiation detection surface of said radiation detector;
and
wherein said frame member is a handle forming an outer appearance that is a circle.
