摘要： The present invention relates to determining changes in the X-ray emission yield of an X-ray tube, in particular determining dose degradation. In order to provide determination of such changes, an X-ray source is provided comprising a cathode, an anode; and at least one X-ray sensor (16). The cathode emits electrons towards the anode and the anode comprises a target area on which the electrons impinge, generating X-ray radiation. An X-ray barrier (24) is provided with an aperture (26) for forming an emitting X-ray beam from the X-ray radiation, wherein the emitting X-ray beam has a beam formation (30) with a central axis. The at least one X-ray sensor is arranged within the beam formation and measures the X-ray intensity for a specific direction of X-ray emission with an angle with respect to the central axis. The at least one X- ray sensor can be positioned inside the beam formation (30), but outside the "actual field of view" (40) as determined by a diaphragm (36).

摘要： 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.
