Abstract

The present disclosure relates to a method for identifying a prompt-γ event, which includes: obtaining first time-of-flight (TOF) data of multiple double coincidence events detected by a detector device; determining second TOF data of one or more triple coincidence events based on the first TOF data, performing verification operations on the second TOF data of the triple coincidence events to determine a prompt-γ event in each of the triple coincidence events. The embodiments of this application can effectively identify prompt gamma photon events by using TOF data, which is helpful for separating dual-nuclide signals.
