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.

Abstract: An X-ray detector includes a direct-conversion converter element and an evaluating unit in a stacked arrangement. In an embodiment, the X-ray detector includes a voltage source, configured to provide a first potential and a second potential different from the first potential; a pulse generating unit for generating voltage pulses; and a connecting unit, for applying the voltage pulses onto the first potential, configured at the output to provide a pulsed potential. In an embodiment, through the application of the pulsed potential to a first surface of the direct-conversion converter element and through the application of the second potential to a second surface of the converter element opposed to the first surface, a pulsed potential difference is formed in the direct-conversion converter element.
