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

摘要

An X-ray detector includes a direct-conversion converter element and an evaluating unit in a stacked arrangement. In an embodiment, the X-ray detector includes a voltage source, configured to provide a first potential and a second potential different from the first potential; a pulse generating unit for generating voltage pulses; and a connecting unit, for applying the voltage pulses onto the first potential, configured at the output to provide a pulsed potential. In an embodiment, through the application of the pulsed potential to a first surface of the direct-conversion converter element and through the application of the second potential to a second surface of the converter element opposed to the first surface, a pulsed potential difference is formed in the direct-conversion converter element.
