ABSTRACT:
A receptacle (3, 13) for an anti-scatter grid (4) and the anti-scatter grid (4) of a catapult grid drawer (1) are constructed such that the anti-scatter grid (4) is held in the receptacle (3, 13) only in a predetermined orientation. In accordance with one variant, guides (5, 6) of the receptacle (3) cooperate with edges (7, 8, 9, 10, 11, 12) of the anti-scatter grid (4) so that together they form a key and slot connection. In accordance with a further variant of the invention, e.g. the anti-scatter grid (4) is provided with a machine-readable code (14). A reader (15) for the code (14) as well as a lock (19) controlled by a signal from the reader (15) are provided in the region of the receptacle (13). The lock (19) releases the access to the receptacle (13) only if the predetermined orientation between the grid (4) and the receptacle (13) exists.
