ABSTRACT: The complete plane of examination is irradiated in its entirely in third-generation computer tomography apparatus. The radiation behind the object is measured by means of a large number of detection elements The reconstruction of the absorption distribution in the plane of examination is inaccurate in a region around the centre of rotation, if the sensitivity of the detection elements differs relative to each other. The invention provides im- proved reconstruction accuracy also in this region, in that the detection device comprises a number of detection elements which is larger than necessary for the measurement of the fan-shaped radiation beam per se in a direction parallel to the axis of rotation, the detection device being displaced during the measurement in the direction of the axis of rotation. It is thus achieved that the radiation behind the object is measured each time by other detection elements, so that the differences in sensitivity can be averaged.
