Abstract: A method (100) creates a braze joint (58) between an anode plate (52) and a piece of graphite (56) of an x-ray tube (38). The method (100) includes receiving (102) the anode plate (52) and the piece of graphite (56). A barrier layer (66) and a braze layer (62) are arranged (104, 106, 108) between the anode plate (52) and the piece of graphite (56), where the barrier layer (66) is between the piece of graphite (56) and the brazing layer (62). The barrier layer (66) is heated (110) with the braze layer (62) to create the braze joint (58) between the anode plate (52) and the piece of graphite (56).

Abstract: The present invention relates to filtering of X-ray radiation generated at multiple focal spots. For the generation of multiple-energy X-ray radiation, an X-ray tube (10) for generating multiple-energy X-ray radiation is provided that comprises an anode (12) and a filter unit (14). The anode comprises at least a first (16) and a second focal spot position (18), which are offset from each other in an offset direction (20) transverse to an X-ray radiation projection direction. The filter unit comprises 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, wherein the filter unit is a directional filter adapted in a such a way that at least a first part of 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 at least a second part of a second X-ray beam (32) emanating from the second focal spot position passes the second portions when passing through the filter unit. The second part of the second X-ray beam is larger than the first part of the first X-ray beam. A portion of the parts of the first X-ray beam, which pass through the filter unit via the first portions, and a portion of the second X-ray beam, which passes the second portions when passing through the filter unit, pass through a common area of the filter unit.
