Abstract
An X-ray radiation detector is disclosed for detecting ionizing radiation, in particular for use in a CT system, with a multiplicity of detector elements. In at least one embodiment, each detector element includes a semiconductor used as detector material with an upper side facing the radiation and a lower side facing away from the radiation, at least two electrodes, wherein one electrode is formed on the upper side of the semiconductor by a metallization layer, and the sum of all detector elements forms a base, which has a base normal at each point. In at least one embodiment, the invention is distinguished by the fact that the upper side of the semiconductor has a surface structure with a surface normal at each point, wherein the surface normal at least in part subtends an angle to the base normal. In at least one embodiment, the invention furthermore relates to a CT system provided with an X-ray radiation detector, which advantageously includes a multiplicity of detector elements structured according to at least one embodiment of the invention.
