1. A PET system, comprising:
a detector module configured to receive radiation rays and generate a plurality of light signals in response to the received radiation rays, the detector module comprising:
a scintillator array having N rows of scintillators and M columns of scintillators, each row of scintillators being arranged in a first direction, each column of scintillators being arranged in a second direction;
a first set of photosensors optically coupled to a first surface of the scintillator array, at least one photosensor of the first set of photosensors extending longitudinally in the second direction so as to be optically coupled to two or more scintillators in the second direction and being optically coupled to two or more columns of scintillators, wherein each scintillator in the scintillator array is optically coupled to only one photosensor of the first set of photosensors; and
a second set of photosensors optically coupled to a second surface of the scintillator array, at least one photosensor of the second set of photosensors extending longitudinally in the first direction; and
an electronics module coupled to the detector module and being configured to identify a scintillator within the scintillator array that has interacted with an impinging radiation ray.
