Abstract

A control installation for the dose rate of the x-ray tube and, thus, for the mean brightness of the output image of the x-ray image intensifier is present. Further, switching circuitry is provided, by means of which a preprogrammed rated value for the dose rate is selected, which rated value lies below the dose rate required for a diagnosis.
