Claim 13:
14. The system according to claim 13, wherein the console device is configured to perform:
obtaining, for each single photon annihilation event data group in the original PET scan data, an energy to time-walk-error correlation of a crystal corresponding to the single photon annihilation event data group with respect to a reference crystal;
obtaining a target time walk error corresponding to a target energy value in the single photon annihilation event data group based on the energy to time-walk-error correlation;
determining a sum of a time value in the single photon annihilation event data group and the target time walk error; and
updating the time value in the single photon annihilation event data group to a value of the sum.
