Signal multiplexing is necessary to reduce a large number of readout channels in positron emission tomography (PET) scanners to minimize cost and achieve lower power consumption. However, the conventional weighted average energy method cann...
A New Pulse Pileup Rejection Method Based on Position Shift Identification [0.03%]
基于位置偏移识别的新脉冲堆积拒绝方法
Z Gu,D L Prout,R Taschereau et al.
Z Gu et al.
Pulse pileup events degrade the signal-to-noise ratio (SNR) of nuclear medicine data. When such events occur in multiplexed detectors, they cause spatial misposition, energy spectrum distortion and degraded timing resolution, which leads to...
