Abstract

Disclosed is a computed tomography device (2) comprising a holding frame (6) and a ring mount (4), being movably mounted to the holding frame (6). The ring mount (4) includes an x-ray detector (10), 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 (40), set up to supply power, in an operating state of the computed tomography device, to a first lot (60) of components of the computed tomography device, the first lot (60) of components being arranged on the ring mount (4) for an image generation process; and a second power supply (50), separable from the first power supply in terms of circuitry, to supply power to a second lot (62) of components of the computed tomography device in a resting state of the computed tomography device, the components of the second lot (62) being set up to hold the semiconductor material in the equilibrium.

Description

technical field [0001] The invention relates to a computed tomography (CT) having a holder and a slewing ring movably mounted relative to the holder, wherein the slewing ring has an X-ray detector with a semiconductor material capable of measuring The occupied state operates in a balanced manner and wherein the CT has a current source arranged to supply power to a certain set of components of the CT in the operating state of the CT which are arranged on the slewing ring for the image generation process. The invention also relates to a method for operating such a CT. Background technique [0002] In modern CT, direct conversion X-ray detectors based on eg cadmium telluride or cadmium zinc telluride (or comparable semiconductor materials with similar relevant properties) are used for photon counting applications. After tuning, such detectors exhibit count rate drift, which can cause artifacts in the imaging process. It is essential for the generation of reliable, high-resolu...
