Schittenhelm, R

In an exemplary embodiment, a radiation source emits a radiation beam for penetrating the layer to be examined from different directions. A radiation receiver supplies electric output signals corresponding to the transmitted radiation intensity. A computer calculates the attenuation values of specific image points of the irradiated body layer based on the output signals. Correction devices are provided in the radiation receiver with which the radiation quality (Mean energy) of the radiation striking the device is determined; each correction device preferably consists of a plurality of detectors arranged behind one another in the direction of the radiation, which detectors can be separated from one another by means of absorber layers. The output signals of the correction detectors serve for determining a correction for the radiation hardening in the patient.
