Abstract: The present invention relates to X-ray generating technology in general, in particular, it relates to an anode disk element (1) for an X-ray generating device (21). The generation of electromagnetic radiation may be considered to be quite inefficient, since a substantial part of energy applied to a focal track is converted to heat rather than X-radiation. Thus, a limiting factor in the operation of X-ray tubes is the cooling of the anode element and more specifically the focal track. In the present invention, an anode disk element is provided, with an improved dissipation of heat from the focal track. Thus, the anode disk element may sustain increased heat while maintaining structural integrity. The anode disk element (1) comprises at least a first surface (2) and a second surface (3), with the first surface (2) comprising a focal track (4) and the second surface (3) comprising a conductive coating (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The first surface (2) comprising the focal track (4) and the second surface (3) comprising the conductive coating (5) are adjacently arranged.

Abstract: An alloy comprising at least two refractory metals and a method for forming such alloy are proposed. In the alloy, a first refractory metal such as tantalum forming a minor portion of the alloy is completely dissolved in a second refractory metal such as tungsten forming a major portion of the alloy. The alloy may be formed by providing the two refractory metals in a common crucible (step S1), melting both refractory metals by application of an electron beam (step S2), mixing the molten refractory metals (step S3) and solidifying the melt (step S4). Due to the possible complete mixing of the refractory metal components in a molten state, improved material properties of the solidified alloy may be achieved. Furthermore, due to the use of tantalum instead of rhenium together with tungsten, a cheap and resistant refractory metal alloy may be produced, which alloy may be used for example for forming a focal track region of an X-ray anode.

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.
