Abstract:
1. An X-ray computed tomography apparatus, comprising: a first X-ray tube configured to generate X-rays with which a subject to be examined is irradiated; a first X-ray detector configured to detect X-rays transmitted through the subject; a second X-ray tube which generates X-rays with which a treatment target of the subject is irradiated; a rotating mechanism which rotates said first X-ray tube, said first X-ray detector, and said second X-ray tube around the subject; a reconstructing unit configured to reconstruct an image based on data detected by said first X-ray detector; and a support mechanism configured to support said second X-ray tube such that a central axis of X-rays from said second X-ray tube tilts with respect to a body axis of the subject, wherein said support mechanism supports said second X-ray tube to allow said second X-ray tube to freely move along the body axis of the subject.
