    摘要: According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a detector, a first DAS, and a second DAS. The radiation detector includes a plurality of detection elements. Each detection element repeatedly detects X-rays generated by the X-ray tube and transmitted through a subject and repeatedly generates an electrical signal corresponding to the energy of the repeatedly detected X-rays. The first DAS acquires the electrical signal detected by part of the imaging region of each detection element in the integral mode. The second DAS acquires the electrical signal detected by the other part of the imaging region of each detection element in the photon count type mode.

    摘要: An X-ray computed tomography apparatus for providing information of alignment, comprises an X-ray generator, an X-ray detector, and a controller. The X-ray generator generates an X-ray. The X-ray detector comprises a plurality of detecting segments in a slice direction and detects the X-ray generated by the X-ray generator. The controller provides the information of alignment between the X-ray generator and the X-ray detector in the slice direction on the basis of a detection information obtained from at least two of the detecting segments, wherein each of the at least two of the detecting segments is at least partially covered by a penumbra of the X-ray.
