Abstract

The invention relates to a diagnostic radiology setup with means for suppressing stray radiation and with an image intensifier television chain with image storing means. There is provided a perforated diaphragm of radiation-absorbing material near the tube, which diaphragm can be introduced into the ray path selectively. Two image memories for an X-ray picture with a diaphragm and an X-ray picture without a diaphragm and an image processing system serve for comparing the image information of the two X-ray pictures to determine and eliminate the stray radiation component.
