Abstract
The present disclosure relates to devices, systems and methods for determining a position of a photon gamma interaction in a PET detector. The PET detector may include a crystal array and a single-end read-out structure. The single-end read-out structure may include a photon-sensor array optically coupled with the crystal array. The crystal array may include a plurality of crystal elements arranged along a first direction and a second direction. The crystal elements may form a plurality of crystal groups along the first direction. The PET detector may further include a plurality of optical separators of the same or different lengths configured to control light transmission in the PET detector. The position of the photon gamma interaction in a crystal group may be determined based on output information of the photon-sensor array optically coupled with the crystal group.
