Abstract
An X-ray diagnostics installation has a mechanism for positioning an examination subject within an X-ray beam and an X-ray image intensifier video chain with an image memory for displaying the radiated regions of the examination subject. A marker indicating the current position of the positioning mechanism is superimposed on the screen image of a visual display unit, thereby permitting adjustment of the position of the examination subject to a desired location without subjecting the patient to unwanted X-ray doses.
