Abstract:
1. A radiation detector comprising: scintillator pixels each having a radiation-receiving end, a light-output end, and reflective sides extending therebetween, the reflective sides having a reflection characteristic varying between the radiation-receiving end and the light-output end such that a lateral spread of light emanating from the light-output ends of the scintillator pixels responsive to a scintillation event generated in one of the scintillator pixels depends upon a depth of the scintillation event in the scintillator pixel, wherein each reflective side has a reflectivity distributed between the radiation-receiving end and the light-output end, the reflectivity nearest the radiation-receiving end having the highest reflectivity; and a plurality of light detectors optically communicating with the light-output ends of the scintillator pixels to receive light produced by scintillation events.
