Abstract

A direct-conversion x-ray detector or x-ray detector module includes: a direct converter; at least one collimator; and at least one radiation source. The at least one collimator is arranged in a direction of radiation of the x-ray radiation in front of the direct converter, and to restrict direct irradiation of the direct converter by the x-ray radiation. The at least one radiation source is at a side of the direct converter, and configured to irradiate the direct converter with additional radiation. The at least one collimator includes: at least one reflection layer on a side facing the direct converter, and configured to reflect the additional radiation onto the direct converter; and a cooling facility configured to cool the at least one radiation source.
