It is described a device (10) for non-symmetrical X-ray beam collimation of a X-ray tube (30), wherein the device comprises a housing (1), a X-ray absorbing plate (2) for collimating a x-ray asymmetrically, and a sleigh (3) for moving the X-ray absorbing plate. With the inventive device an asymmetrical X-ray beam can be obtained from a symmetrical X-ray beam, such that the device can be used in conventional symmetrical X-ray systems, like C-arm systems and that a better protection of a patient is reached. |
