The processing electronics includes a comparator for recognizing faulty detector signals by means of which the roll-in of data ito the image memory is controllable such that, given a faulty detector signal, the transfer of the information into a memory line allocated to the detector is inhibited. The x-ray scanner also includes an allocator unit which omits predetermined detector channels for the purpose of geometric balancing. Given outage of a detector, its detector channel is omitted by the allocator unit, based on a signal from the comparator, instead of a prescribed detector channel. | |
