ABSTRACT:
In an exemplary embodiment, two radiation detectors are arranged behind the radiography subject. One of the detectors is covered by a radiation filter. A different radiation attenuation along the radiation paths of the respective detectors thereby takes place, so that, through division of the output signals of the detectors, a quotient signal can be obtained which corresponds to the radiation transparency of the radiography subject.
