Abstract: An X-ray scanning system for high speed imaging of an object using an X-ray source for generating a fan shaped X-ray beam (12) for traversing a linear section or slice of the object, and a linear array of detectors (14) on the opposite side of the object (10) from the source which generate light depending on the X-ray image incident thereon, wherein optical fibers (16) link the detectors to the input of an image intensified CCD camera (18), the fiber ends forming a planar array having an aspect ratio which is different from that of the linear array of detectors and which matches the aspect ratio of the camera, the detector array having an addressable array of N.times.
