Abstract:
1. An X-ray computer tomography system comprising: an X-ray tube for producing X-rays; an X-ray detector having a plurality of detector modules each having a plurality of detector elements arranged in a matrix, the detecting elements being adapted to detect X-rays transmitted through a subject to be examined; a support mechanism by which the X-ray tube and the X-ray detector are held so as to be rotatable about an axis of rotation; a reconstruction unit for reconstructing images based on an output from the X-ray detector; and a display portion for displaying the reconstructed images; wherein each of the detector modules is arranged along a reference axis substantially perpendicular to the axis of rotation and individually tilted relative to the axis of rotation by an angle of tilt, and the detector modules are arranged such that each detector module is fixed at a contact point which is offset a distance from the contact point of an adjacent detector module.
