Claim 11:
12. The system according to claim 11, wherein the console device is configured to perform:
for each single photon annihilation event data group in the PET scan data, searching the PET scan data for a target single photon annihilation event data group which matches with the single photon annihilation event data group, wherein the target single photon annihilation event data group satisfies the following conditions:
a distance between a first spatial position indicated by spatial position information in the target single photon annihilation event data group and a second spatial position indicated by the single photon annihilation event data group is less than a preset distance threshold;
a difference between first time indicated by time information in the target single photon annihilation event data group and second time indicated by the single photon annihilation event data group is less than a preset time threshold; and
a first energy value in the target single photon annihilation event data group and a second energy value in the single photon annihilation event data group are both smaller than the first energy threshold; and
if the target single photon annihilation event data group is searched out, determining that the target single photon annihilation event data group and the single photon annihilation event data group belong to a first scan data set corresponding to the same intra-crystal Compton scattering event.
