DEVICE TO GENERATE SCANNING X-RAY PYRAMID-SHAPED BEAM (VERSIONS) Russian patent published in 2010 - IPC H05G1/02 

FIELD: physics.

SUBSTANCE: proposed device comprises X-ray tube, a radiation source, emitting X-ray radiation from its actual focal spot, pyramid-shaped spot beaming unit and X-ray radiation receiver. Note that pyramid-shaped spot beaming unit consists of two collimators with one through hole with its shape repeating geometrical figure formed by intersection of casing with pyramid with its apex located at the center of actual focal spot of anode and its base representing X-ray radiation receiver detector. Note also that X-ray radiation and both collimators are secured on holder arranged to rotate about vertical axis passing through the center of the center of actual focal spot of tube anode, while X-ray source with protective shield are fixed.

EFFECT: better protection of patients and personnel, simplified design.
