Abstract

An X-ray detector with photon-counting directly converting detector elements and a method for the temperature stabilization of at least one detector element of an X-ray detector of a CT system are disclosed, wherein the detector elements use a sensor material which converts incident photons of radiation directly into free-moving charge in the sensor material and wherein with the aid of a circuit arrangement (e.g. an ASIC), the number of incident photons in relation to predefined energy ranges (e.g., to imaging) is determined, wherein the total electrical power of at least one detector element is kept constant regardless of the incident intensity of radiation.
