Title:
SYSTEMS AND METHODS FOR DETERMINING TRUE COINCIDENCE EVENTS
Document Type and Number:
WIPO Patent Application WO/2020/211764
Kind Code:
A1
Abstract:
Systems and methods (1200) for determining true coincidence events are presented. The systems and methods (1200) may determine original coincidence events based on time of occurrence of a plurality of single events (1201). The systems and methods (1200) may also determine random coincidence events by processing the plurality of single events based on cycle offsets of detector units that detect the plurality of single events (1203). A difference of any two cycle offsets may be greater than a predetermined coincidence window width. The systems and methods (1200) may then determine the true coincidence events based on the original coincidence events and the random coincidence events (1205).
