On-line energy coincidence method and system for all-digital PET system
Q Xie, X Wu, J Zhu, M Niu, Z Hu, W Luyao - US Patent 10,149,657, 2018 - Google Patents
An on-line energy coincidence method for an all-digital PET system, comprising: a detection
module conducting information collection on a scintillation pulse, forming a single event data
frame and sending it to an upper computer; the upper computer conducting two-bit position
distribution statistics on an incident gamma photon event and conducting position spectrum
partition; performing statistics on an energy distribution spectrum of each crystal bar, so as to
acquire an energy correction value; the detection module uploading a crystal bar partition …
