X-ray apparatus for computer tomography. Strip-shaped visible images which correspond to the individual X-ray exposures in one image plane are transferred to the light-sensitive input of an image pick-up tube by means of a lens system. The lens system comprises at least one lens, interposed between the image plane and the light-sensitive input layer of the image pick-up tube, which produces an astigmatic optical path.
