摘要：
A method of calibrating time in a Positron Emission Computed Tomography (PET) device includes determining a rising edge slope of an electrical signal corresponding to a photon which is detected by a detector of the PET device when the PET device is used to scan a part of a subject to be examined. The method includes determining a time shift corresponding to the rising edge slope based on a correspondence between the rising edge slope and the time shift； calibrating time information of the photon based on the time shift； and reconstructing a PET image of the part of the subject to be examined based on the calibrated time information of the photon.
