Abstract

The invention relates to a method for detecting x-rays (R) using an x-ray detector (100) which has a direct-conversion semiconductor detector element (150a, 150b). Additional radiation (K) is supplied to the semiconductor detector element (150a, 150b) using a radiation source (210a, 210b), and the supply of the additional radiation (K) is controlled and / or regulated on the basis of a specified target value (Ta, Tb, Tc). In particular, the target value can be specified in a variable manner over time as a sequence of target values. The invention further relates to an x-ray detector system (200) with which the method can be carried out.

Description

technical field

[0001] The invention relates to a method for detecting x-ray radiation, an x-ray detector, an x-ray detector system and a computed tomography with a direct conversion semiconductor detector element for detecting x-ray radiation system. Background technique

[0002] For detecting X-ray radiation, different detector systems are known. For example, scintillation crystal detectors are widely used in order to be able to detect the flux density of x-ray radiation occurring in the field of computed tomography. The scintillation crystal detector firstly converts the X-ray radiation photochemically into photons which have a suitable energy in order to enable detection of the photons by means of semiconductor diodes (photodiodes), for example.

[0003] Furthermore, for computed tomography, efforts are being made to use so-called direct-conversion semiconductor detection elements, which absorb the X-ray radiation in the semiconductor material without prior energy conv...
