Abstract
A scintillation detector according to an embodiment of the invention features a monolithic scintillation crystal and a plurality of optical fibers coupled to the scintillation crystal. The optical fibers are arranged to convey scintillation light to an optical sensor that is located exterior to the scintillation crystal. Because the optical fibers are extremely small in diameter, a multiplicity of them can be coupled to the scintillation crystal to provide the extremely high resolution of a pixelated scintillation crystal while the comparative manufacturing simplicity of a monolithic scintillation crystal is maintained. In preferred embodiments, the optical fibers are further arranged so that depth of interaction information can be obtained.
