Abstract
An X-ray device for an inverse computer tomography configuration, includes a plurality of X-ray emitters and a detector arranged opposite the X-ray emitters. The X-rays emitted by the X-ray emitters can be detected by the detector after at least partly passing through an examination region located in the intermediate region between the X-ray emitters and the detector. In an embodiment, the X-ray emitters are grouped into at least two mutually spaced sub-arrangements. Each sub-arrangement comprises multiple X-ray emitters. The spacing between the at least two sub-arrangements is greater than the spacing between adjacent X-ray emitters of at least one of the sub-arrangements.
Claims20
An X-ray device for an inverse computed tomography configuration, comprising:
- a plurality of X-ray emitters;
- and
- a detector arranged opposite the plurality of X-ray emitters, wherein after passing through at least some of a region of interest located in an intermediate region between the plurality of X-ray emitters and the detector, the X-rays emitted by the plurality of X-ray emitters are detectable by the detector, the plurality of X-ray emitters being arranged, in an arrangement other, than equidistant from one another in series, into at least two mutually spaced sub-arrangements, each of the at least two mutually spaced sub-arrangements including a plurality of X-ray emitters, and a spacing between the at least two mutually spaced sub-arrangements being greater than a spacing between adjacent X-ray emitters of at least one of the at least two mutually spaced sub-arrangements, wherein a region irradiatable by the plurality of X-ray emitters of the respective sub-arrangement is limited to a respective partial region, of a plurality of partial regions, of a maximum cross-sectional area of the region of interest that is irradiatable, and wherein the plurality of partial regions, taken in their entirety, completely cover the cross-sectional area of the region of interest.
