Claim 11:
12. An X-ray computed tomography apparatus comprising:
a gantry including an imaging system configured to perform an imaging process on a subject by using radiation;
a couch having a couchtop on which the subject is placed; and
a processor configured to
generate a first image acquired by imaging the gantry and the couchtop of the couch on which the subject is placed while using an optical imaging device different from the imaging system,
calculate, on a basis of a relative positional relationship between the gantry and the couchtop in the first image, at least one of position or angle of an imaging plane in the first image, the imaging plane being a plane related to an imaging position used in the imaging process by the imaging system, and
generate a second image by combining the first image with the imaging plane on a basis of the calculated at least one of position or angle.
