摘要： A computed tomography scanner is disclosed for performing a spiral scan. In at least one embodiment, the computed tomography scanner includes a rotatable X-ray emitter for generating a beam fan and an X-ray detector, positioned diametrically opposite to the emitter, and an associated evaluation unit. In at least one embodiment, provision is made for an X-ray filter arranged downstream of the X-ray emitter, the position of the X-ray filter being correlated to that of the X-ray detector. Further, the X-ray filter is partly inserted into the beam fan only during operation for generating an unfiltered and, simultaneously, a filtered radiation component of the beam fan, wherein the radiation components have different X-ray spectra and wherein the evaluation unit is designed for separate evaluation of a measurement signal of the unfiltered radiation component and a measurement signal of the filtered radiation component, to obtain dual-energy images.

摘要： A tomosynthesis apparatus has an x-ray source that generates an x-ray beam emanating from a focus, which is received by a flat panel detector. To set a tomosynthesis angle, the position of the central axis of the x-ray beam of the x-ray source is variable. A collimator diaphragm has a diaphragm aperture that limits the expansion of the x-ray beam at the location of the flat panel detector. The collimator diaphragm is arranged in the beam path between the focus and the flat panel detector. The shape and size of the diaphragm aperture are dynamically varied (adjusted) dependent on the changing tomosynthesis angle, such that the expansion of the x-ray beam at the location of the flat panel detector always essentially corresponds to the detector dimensions.

摘要： A multi-beam x-ray device has a multi-beam x-ray tube with an interior in the form of a circle. Focal spots of the x-ray radiation are arranged along the circle. An x-ray tube control unit controls the x-ray radiation emission such that an x-ray beam is emitted from each segment of the circle in specified sequence. The circle is divided up into at least two segments, and multiple diaphragms, each with at least one diaphragm aperture therein, one mounted to rotate around the center point of the circular path into the beam path of the x-ray tube. A first diaphragm, whose first diaphragm aperture limits the cross section of the x-ray beam emitted from the x-ray tube, is associated with each segment of the circular path. A number of slice images can be acquired without a movement of the x-ray tube.

An x-ray tube control unit controls the x-ray radiation emission such that an x-ray beam is alternately emitted from each polygon side in a specified sequence. Multiple first diaphragms with at least one respective first diaphragm aperture are arranged such that they can move into the beam path of the x-ray tube. A first diaphragm, whose first diaphragm aperture limits the cross section of the x-ray beam emitted from the x-ray tube, is associated with every polygon side. A number of slice images can be generated from different directions without a movement of the x-ray tube.
