Abstract
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 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.
