Abstract
In an exemplary embodiment, a radiation detector for receiving the radiation emerging from the radiography subject delivers electrical output signals corresponding to the received radiation profile, generating a relative movement between the support device and the radiation beam, and with a measurand converter and a video unit for the formation of the X-ray shadow image. The radiation detector is an X-ray image intensifier with an outlet-connected television camera. A cancellation device is present which cancels the formation in the target region which is disposed immediately before the line image in the direction of movement of the line image, generated by the X-ray beam, on the target. The effect of the stray radiation on the image quality is thereby eliminated.
