ABSTRACT:
A drive mechanism for the anti-scatter grid of an X-ray apparatus, notably a tomography apparatus.
For focussing the grid with respect to the X-ray source, use is made of a pin which engages a diametrical groove provided in a drive disc. The disc is coupled to the rotatably arranged grid. So as to avoid overloading of the pin, the groove is provided with a run-out, while the pin is connected to the disc by way of a resetting member which also serves as an alternative drive for the disc.
