| Abstract: |
A novel high resolution scintillation detector array for use in radiation imaging such as high resolution Positron Emission Tomography (PET) which comprises one or more parallelepiped crystals with at least one long surface of each crystal being in intimate contact with a semiconductor photodetector such that photons generated within each crystal by gamma radiation passing therethrough is detected by the photodetector paired therewith.

What is claimed is:
1. A gamma ray radiation device, comprising at least one scintillation crystal each said crystal generating scintillation radiation as gamma radiation passes therethrough having at least one long, narrow surface, at least one said long narrow surfaces being coated with a semiconductor photodetecting device, a means for recording scintillation radiation being connected thereto, greater than about 80% of the scintillation radiation generated being detected by the photodetecting device.
