Abstract
An X-ray diagnostics installation has an X-ray tube for directing an X-ray beam at an examination subject disposed within the beam path on a support plate, the support plate having a secondary radiation grid on one side thereof, and having a receptacle therein for an X-ray film cassette. The support plate is mounted so as to be rotatable about an axis which is perpendicular to a central ray of the X-ray beam such that the secondary radiation grid can be optionally disposed in front of or behind the X-ray film cassette as viewed in the radiation direction, while the film focus distance remains the same.
