There is disclosed an X-ray computer tomography system having an X-ray tube for producing X-rays, an X-ray detector including plural detector modules, a rotation 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 the output from the detector, and a display unit for displaying the reconstructed images. Each of the detector modules has plural detector elements arranged in a matrix. The detector elements act to detect the X-rays transmitted through a subject to be examined. The detector modules are arranged along a reference axis substantially perpendicular to the axis of rotation and tilted relative to the axis of rotation.
