X-ray detector with voltage sources device for generating a pulsed potential difference

摘要

The present invention relates to an x-ray detector (23) comprising a directly - converting converter element (53) and an evaluation unit (59) in a stacked arrangement, and a voltage sources device (1). The voltage sources device (1) comprises a voltage source (3), which is designed a first potential (5) and a of the first potential (5) the second potential (7) is different to provide. ). The voltage sources device (1) further comprises a pulse generation of a unit (11) for the production of voltage pulses (12), and a connecting unit (9) for imparting the voltage pulses (12) to the first potential (5), wherein the connecting unit (9) at the output is designed in such a way, a pulsed potential (6) to provide. By the application of the pulsed potential (6) to a first surface of the directly - converting converter element (53) and by the application of the second potential (7) to one of the first surface opposite second surface of said (53), a pulsed potential difference in the directly - converting converter element (53) formed.
