摘要： 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.

摘要： A direct conversion X-ray detector for the detection of X-rays includes at least a semiconductor used for detecting X-rays, which has areas that are shaded against X-rays and unshaded areas, a pixelated electrode attached to the semiconductor and an all-over electrode attached to the semiconductor opposite the pixelated electrode, and at least one light source to illuminate the all-over electrode with additional light radiation for the purpose of generating additional charge carriers. In an embodiment, the at least one light source is designed such that the shaded areas are irradiated with a different intensity of the additional light radiation than are the unshaded areas. A CT system including the direct conversion X-ray detector is also disclosed, together with a method for the detection of incident X-rays via direct conversion X-ray detector, wherein the shaded areas are irradiated with a different intensity of the additional light radiation than the unshaded areas.

摘要： In a method and control unit for activating an X-ray detector, having an X-ray sensitive sensor layer and an arrangement of pixel electrodes connected at the back to the sensor layer, an individually adjusted depletion voltage is applied to each of the pixel electrodes. The value of the depletion voltages applied to different pixel electrodes is chosen to be different such that the effective pixel sizes respectively associated with the pixel electrodes are aligned with each other.

摘要： An X-ray detector is disclosed. According to an embodiment of the invention, the X-ray detector includes at least two adjacently arranged detector elements, to each of which a high voltage is applied in order to detect incident X-rays. In this case, two adjacent detector elements are coupled to one another by way of a protection circuit, designed to limit a voltage difference between the two adjacent detector elements to a voltage value which is non-critical with regard to the formation of a flashover between the two detector elements.
