1. a PET detection system, it is characterized in that, described PET detection system comprises the detector rings and pixel identification system that are made up of at least two detector modules, described detector module comprises the crystal array be made up of M crystal unit, the photoelectronic detecting array be made up of N number of photodetector and at described crystal array and the beam path alignment unit corresponding respectively with each crystal unit between described photoelectronic detecting array, wherein, M and N be greater than 1 integer and M is greater than N;

  • Described crystal unit, for becoming visible ray by the γ

    received photon conversion;

    Described beam path alignment unit, for converging the visible ray of the described crystal unit outgoing received;

    Described photodetector, converts the signal of telecommunication to for the visible ray converged by the described beam path alignment unit received;

    Described pixel identification system, the signal of telecommunication for exporting according to described photodetector determines the positional information of the crystal unit receiving described γ

    photon, and determines the resolution of described PET detection system according to described positional information.
