APPARATUS AND METHOD FOR DETECTING X-RAY RADIATION WITH BACKGROUND SUPPRESSION,VORRICHTUNG UND VERFAHREN ZUR DETEKTION VON RÖNTGENSTRAHLUNG MIT HINTERGRUNDUNTERDRÜCKUNG

An X-ray detector apparatus 100 for detecting incoming X-ray photons of X-ray radiation to be sensed, comprises an X-ray detector device 10 having an X-ray detector section 11 and an entrance section 12, wherein the X-ray detector section 11 is arranged for detecting the X-ray photons incoming through the entrance section 12 by creating photo electrons in response to an interaction of the incoming X-ray photons with the X-ray detector section 11 and for providing an X-ray output signal, which is determined by the detected X-ray photons, and a background suppression device 20 being configured for suppressing background contributions in the X-ray output signal which are caused by at least one of escape electrons being emitted from the X-ray detector device 10 in response to an absorption of the X-ray radiation and external electrons occurring outside the X-ray detector device 10. Furthermore, an X-ray detection method is described.
