A method for determining a pair of compliance events is provided. A set of event data collected by a PET detector may be divided into N sub-sets, and each of the N sub-sets of event data may be sorted according to an occurrence time of each event included in the event data, wherein N is an integer greater than or equal to 2. A K stage heapsort may be performed on the sorted N sub-sets of event data according to the occurrence time of each event, so as to sequentially output data of each event in the sorting order, wherein K is an integer greater than or equal to 1. A time compliance determination and a space compliance determination may be performed on the sequentially-outputted event data, and a pair of compliance events may be determined if both the time compliance determination and the space compliance determination are passed.
