A counting x-ray detector includes a converter element, a rewiring unit and an evaluation unit including pixel electrodes. In an embodiment, the converter element includes a first electrode on a surface facing away from the evaluation unit and a pixelated second electrode having a plurality of electrode elements on a surface facing toward the evaluation unit. The rewiring unit is on a surface of the converter element facing toward the evaluation unit. First contacts of electrically conductive connections between the electrode elements and the pixel electrodes are provided on a surface of the rewiring unit and include a first areal distribution; and second such contacts are provided on a surface of the rewiring unit, including a relatively smaller second areal distribution. An areal extent of the evaluation unit is relatively smaller than an areal extent of the converter element.

A direct-converting x-ray radiation detector is disclosed for detecting x-ray radiation, in particular for use in a CT system. In an embodiment, the detector includes a semiconductor material used for detecting the x-ray radiation; at least one collimator; and at least one radiation source, to irradiate the semiconductor material with additional radiation. In at least one embodiment, the at least one collimator includes at least one reflection layer on a side facing the semiconductor material, on which the additional radiation is reflected to the semiconductor material. In another embodiment, a CT system including the direct-converting x-ray radiation detector, and a method for detecting incident x-ray radiation via a direct-converting x-ray radiation detector, in particular for use in a CT system, are disclosed.
