Abstract

In the exemplary embodiments, a radiation measuring arrangement which includes radiation source is rotated for irradiating the radiography subject from different directions. A measured value converter calculates a layer image from the output signals of the detectors of the radiation receiver. For shielding against stray radiation, two hollow cylinders of equal diameter and with a common axis and comprised of a radiation-absorbing material lie between the radiation source and the radiation receiver, a gap for the passage of the x-ray beam being left therebetween. The radiography subject is introduced into the hollow cylinders.
