ABSTRACT:
In an exemplary embodiment, there is provided a patient support, a radiation measuring arrangement including a radiation source which generates at least one fan-shaped radiation beam, penetrating the radiography subject, and a radiation receiver which has an array of detectors which are connected to a signal processing circuit, and means for generating relative movement between the patient support and the radiation measuring arrangement in a longitudinal direction of the support, for the generation of a shadow image several radiation directions are generated so that a plurality of intersection points of the radiation paths result within an image exposure region. The signal processing circuit determines the radiation transparency in the patient for every intersection point of a plane parallel to the patient support.
