Abstract

A radiation- sensitive detector includes a photosensor elements (122) and a scintillator (116) optically coupled to the photosensor element (122). The scintillator (116) includes a powdered scintillator and a resin mixed with the powdered scintillator. The refractive index mismatch between the powdered scintillator and the resin is less than 7%. In one non-limiting instance, the composite scintillator material may be used to form fiber optic leaves arranged as a high-resolution detector array in conventional or spectral CT.
