More Information
Summary:The embodiments of the present disclosure provide a state detection method and system for an imaging device. The method includes: obtaining a first background event of a crystal of a detector of the imaging device, the first background event being related to an inherent radiating particle of the crystal; correcting a crystal position look-up table based on the first background event; correcting an energy state of the imaging device; obtaining the second background event of the crystal, the second background event being related to the inherent radiating particle of the crystal; and correcting a state of time of flight of the detector based on the first background event and the second background event.
