摘要： 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.

摘要： An X-ray tube of an embodiment includes an anode; and an electron emission device. In an embodiment, the electron emission device includes at least one electron emitter including at least one emission surface and at least one barrier grid, the at least one barrier grid being spaced apart from the at least one emission surface of the electron emitter and includes a definable number of individually controllable grid segments. According to an embodiment, at least one individually definable grid voltage is applicable to each of the grid segments. In a simple manner, an electron-emission device of an embodiment permits the image quality to be adjusted with minimal anode loading.

摘要： An x-ray tube includes an electron emitter to emit an electron beam; and a multilayer anode including a first anode layer facing the electron beam and a second anode layer facing away from the electron beam. The first anode layer includes a first anode material to generate a braking radiation via the electron beam and the second anode layer includes a second anode material to generate a further x-ray radiation via the braking radiation. The further x-ray radiation is relatively more monochromatic than the braking radiation and wherein the first anode layer and the second anode layer adjoin in a planar manner.

摘要： An anode has a base member, on which an X-ray active layer is applied. A first cooling circuit with a first cooling medium extends at least in part in the base member beneath the X-ray active layer. A second cooling circuit with a second cooling medium is arranged beneath the first cooling circuit. The anode exhibits distinctly improved thermo mechanical properties.
