Recently, a novel CdTe photon counting x-ray detector (PCXD) with energy discrimination capabilities has been developed [1, 2]. When such detectors are operated under a high count rate, however, coincident pulses and tails of pulses distort the recorded energy spectrum. These distortions are called pulse pileup effects. It is essential to compensate for these effects on the recorded energy spectrum in order to take a full advantage of spectral information PCXDs provide. In this study, we have… CONTINUE READING
