Abstract

In an exemplary arrangement a rotatable scanning system comprises an X-ray tube which emits a beam of X-rays which penetrates the layer to be examined, and a radiation receiver which supplies electrical output signals corresponding to the measured radiation intensity. A computer is connected to the radiation receiver for calculating the attenuation values of specific image points of the irradiated body layer from the output signals of the radiation receiver. An inductive transformer is provided for transmitting energy to the X-ray tube, its secondary winding being arranged in a fixed position relative to the X-ray tube and rotating with the scanning system and its primary winding being fixed relative to the stationary part of the unit.
