Detection apparatus for detecting photons taking pile up events into account

摘要

pThe invention relates to a detection apparatus (12) for detecting photons. The detection apparatus comprises a pile up determining unit (15) for determining whether detection signal pulses being indicative of detected photons are caused by a pile up event or by a non pile up event wherein a detection values generating unit (16) generates detection values depending on the detection signal pulses and depending on the determination whether the respective detection signal pulse is caused by a pile up event or by a non pile up event. In particular the detection values generating unit can be adapted to reject the detection signal pulses caused by pile up events while generating the detection values. This allows for an improved quality of the generated detection values./p
