X-ray diagnostic system having an X-ray aiming device and an image-intensifier television relay link

摘要

The invention relates to an X-ray diagnostic system having an X-ray tube (1), with a primary radiation diaphragm (11), a patient bed (2), an aiming device (6) for direct recording with means (6a) for selecting the recording format, and an image-intensifier television relay link (4, 5, 8, 10) for reproducing radiographs. A signal generator (12) generates a signal which depends on the respectively selected recording format and is superimposed on the video signal in a mixing stage (9) in the video channel upstream of the VDU (10) in order to fade a frame corresponding to the recording format into the radiograph.
