1. A PET system, comprising:
a detector configured to receive radiation rays, the detector comprising a detecting module, the detecting module comprising:
a scintillator array configured to receive a radiation ray and generate optical signals in response to the received radiation ray, the scintillator array having a plurality of rows of scintillators arranged in a first direction;
a first group of light guides configured to guide the optical signals, wherein the first group of light guides is arranged on a side surface of the scintillator array along the first direction, one of the first group of light guides is coupled to two adjacent rows of the plurality of rows of scintillators in the first direction;
one or more photosensors configured to convert the optical signals into electrical signals; and
at least one processor configured to convert the electrical signals into image information.
