ABSTRACT:
A depth of interaction-sensitive crystal scintillation detector features crystal types that alternate in three-dimensional checkerboard fashion, each type having a different crystal decay time. One or more photosensors are disposed on each of at least two orthogonal surfaces. The scintillation detector provides improved depth of interaction resolution. The different crystal types are identified by pulse shape discrimination processing.
