Abstract
An X-ray computed tomography apparatus includes an X-ray tube () which generates X-rays, a multi-channel X-ray detector () which detects X-rays transmitted through an object to be examined, a rotating frame () which is equipped with the X-ray tube and the X-ray detector, a reconstruction unit () which reconstructs an image on the basis of an output from the X-ray detector, and a control unit () which alternately shifts the X-ray focal spot of the X-ray tube along the rotating direction on the anode by a distance +σ and a distance −σ for each view. The distance σ is set to where SOD is the distance between the X-ray tube and the rotation center, and Δβ is the angle difference between adjacent views, such that X-ray focal spots in the adjacent views overlap each other at almost the same position.
