  • Patent number: 11602323
    Abstract: A computed tomography device includes a holding frame and a ring mount, being movably mounted to the holding frame. The ring mount includes an x-ray detector, with a semiconductor material, operable in an equilibrium of statistical states of occupation. In an embodiment, the computed tomography device includes a first power supply, set up to supply power, in an operating state of the computed tomography device, to a first lot of components of the computed tomography device, the first lot of components being arranged on the ring mount for an image generation process; and a second power supply, separable from the first power supply in terms of circuitry, to supply power to a second lot of components of the computed tomography device in a resting state of the computed tomography device, the components of the second lot being set up to hold the semiconductor material in the equilibrium.

  • Patent number: 11476013
    Abstract: An anti-scatter collimator is for arrangement in a stacked construction with an X-ray detector. In an embodiment, the anti-scatter collimator includes collimator walls arranged adjacently at least along a first direction. The collimator walls are mutually spaced to provide a through-channel between each pair of adjacent collimator walls. The through-channels provided by the arrangement of the multiplicity of collimator walls are at least partially filled with a filler material.

  • Patent number: 10371833
    Abstract: An X-ray detector includes a converter element and a carrier element in a stack arrangement. In an embodiment, the X-ray detector further includes a light source arranged on the carrier element, a light-directing unit formed outside a projection of a planar extension of the converter element in the stacking direction, and a light-directing unit arranged such that a quantity of light emitted from the light source is incident on a surface of the converter element, facing away from the carrier element via a light path.
