    Abstract: A liquid metal (9) is arranged as an x-ray target such that it flows past an electron impact zone (8). A pressure medium (11) is provided in a pressure region (10) that is separate from the liquid metal region (7), and exerts a pressure on the liquid metal (9) in the fluid metal region to drive it past the electron impact zone (8). The pressure region includes a rechargeable pressure accumulator (R3) for applying the pressure. Independent claims are also included for an x-ray emitter, and an x-ray apparatus.

    Abstract: The invention relates to a computed tomography apparatus (CT apparatus) for imaging by means of radiation having traversed an object to be examined (that is, directly transmitted radiation), as well as by means of radiation scattered by the object to be examined, which apparatus includes a radiation source (S), a detector arrangement (16) and a device whereby the radiation (41a) having traversed the object to be examined can be blocked at least to an extent that the intensity incident on the detector arrangement (16) does not substantially exceed the intensity of radiation (41b) scattered by the object (13) to be examined and incident on the detector arrangement (16). The invention enables the detection of scattered radiation (CSCT mode) which is not affected by crosstalk from the transmitted radiation, even when the detector arrangement does not satisfy severe requirements as regards crosstalk properties and/or is configured as a single-row detector arrangement.

    Abstract: An apparatus includes a local minimum identifier (408) that identifies a local minimum between overlapping pulses in a signal, wherein the pulses have amplitudes that are indicative of the energy of successively detected photons from a multi-energetic radiation beam by a radiation sensitive detector, and a pulse pile-up error corrector (232) that corrects, based on the local minimum, for a pulse pile-up energy-discrimination error when energy-discriminating the pulses using at least two thresholds corresponding to different energy levels. This technique may reduce spectral error when counting photons at a high count rate.

    Abstract: It is described a method and a CT system for measuring dual-energy X- ray attenuation data of an object. The CT system comprises a rotatable holder, an X-ray source comprising two different X-ray focus points, and an X-ray detection device comprising a plurality of detector elements exhibiting different spectral sensitivities. The method comprises the steps of (a) adjusting the X-ray source such that it emits X-rays originating a first focus point, (b) acquiring first attenuation data separately with first detector elements and with second detector elements, (c) moving the X-ray focus discretely to a second focus point, and (d) acquiring second attenuation data separately with both types of detector elements. Thereby the two focus points are spatially separated from each such that a first beam path originating from the first focus point penetrates a certain voxel within the object and impinges on a first detector element and a second beam path originating from the second X-ray focus point penetrates the same voxel and impinges on a second detector element.
