ABSTRACT:
An annular radiation receiver consisting of individual detectors, is stationary, and an X-ray source is rotated along a path surrounding the detectors. The individual detectors of the radiation receiver are combined into detector groups having an equal number of individual detectors, and the detector groups are adjustable independently of one another in such a fashion that those individual detectors which are disposed in advance of the radiography subject are respectively moved out of the X-ray beam. To this end, a cam plate can be present which is rotatable synchronously with the rotation of the X-ray beam, to which levers are coupled which control the detector groups.
