Title:
A plurality of focus spot X-rays radiation filtering
Document Type and Number:
Japanese Patent JP6073869
Kind Code:
B2
Abstract:
For the generation of multiple-energy X-ray radiation, an X-ray tube (10) for generating multiple-energy X-ray radiation includes an anode (12) and a filter (14). At least a first (16) and a second focal spot position (18) are offset from each other in an offset direction (20) transverse to an X-ray radiation projection direction. The filter includes a first plurality (22) of first portions (24) with first filtering characteristics for X-ray radiation and a second plurality (26) of second portions (28) with second filtering characteristics for X-ray radiation. The filter is a directional filter adapted in a such a way that at least a first X-ray beam (30) emanating from the first focal spot position at least partly passes through the filter unit via the first portions, and a second X-ray beam (32) emanating from the second focal spot position passes obliquely through the first and the second portions when passing through the filter unit.
