Abstract
Methods and systems for detecting a three-dimensional position of a scintillation event converting a radiation into a light. For example, a system includes a crystal array including a plurality of crystal elements arranged at least along a first direction and a second direction, the plurality of crystal elements extending along a third direction between a first end and a second end, the plurality of crystal elements being configured to receive the radiation entered from the second end; wherein: the plurality of crystal elements is arranged into a plurality of crystal pairs; each of the plurality of crystal pairs optically coupled to one light bridge at the first end extending and bridging light along the first direction; each of the plurality of crystal pairs is optically coupled for the light in the second direction with at least a neighboring crystal pair only through two light tunnels.
