Abstract (en)
[origin: US4803716A] An x-ray diagnostics installation for radiographs has a secondary radiation grid disposed in front of a holder for x-ray film. The secondary radiation grid is moveable during an exposure. Control circuitry controls the speed of movement of the secondary radiation grid dependent on the anticipated exposure time, such that imaging of the lamellae of the secondary radiation grid on the x-ray film is reliably prevented for all exposure times.
