An x-ray diagnostics installation has an x-ray tube and an image processing and display system which includes a video camera connected to the x-ray image intensifier, an image memory, a spatial frequency filter and a monitor. A motion detector is connected to the image memory and to the video camera and controls operation of the spatial frequency filter to vary the filter effect so that the filter effect is greater in transillumination image regions having little motion than in regions having a higher amount of motion.
