Abstract
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.
