Abstract
In an exemplary embodiment, a radiation measuring arrangement has two x-ray tubes of different radiation energy which generate radiation beams penetrating the radiography subject, and also has a radiation receiver which determines the radiation intensity behind the subject. The radiography subject is irradiated from different directions. A computer determines, for every image point, the attenuation coefficient for every radiation energy and determines therefrom the mean ordinal number and the density. The radiation receiver is designed as a stationary detector ring. For scanning only the x-ray tubes are rotated about the radiography subject. They are maintained at such a distance from one another that no detector element is simultaneously impinged upon by both radiation beams.
