THREE-DIMENSIONAL IMAGING DETECTOR EMPLOYING WAVELENGTH-SHIFTING OPTICAL FIBERS

摘要

A detector structure having one or more inorganic scintillating crystals (210) coupled through wavelength shifting optical fibers (WLSFs) (310, 320) to position sensitive photomultipliers (PMTs) (330). By using WLSFs the detector structure can operate with a significant reduction in the number of PMTs and electronic channels, while potentially improving the resolution of the system by allowing three-dimensional reconstruction of energy deposition positions.
