摘要：
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, to acquire an energy correction value the detection module uploading a crystal bar partition data table and an energy peak correction data table starting information collection of on-line energy correction when an event is coming, according to a two-dimensional coordinate thereof, from the crystal partition table, searching for a crystal bar number corresponding thereto, and searching for an energy correction value from the energy correction table and sending data passing the energy coincidence to the upper computer.
