Abstract
For the generation of multiple-energy X-ray radiation, an X-ray tube () for generating multiple-energy X-ray radiation includes an anode () and a filter (). At least a first () and a second focal spot position () are offset from each other in an offset direction () transverse to an X-ray radiation projection direction. The filter includes a first plurality () of first portions () with first filtering characteristics for X-ray radiation and a second plurality () of second portions () 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 () 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 () emanating from the second focal spot position passes obliquely through the first and the second portions when passing through the filter unit.
