A scintillator, for use in a radiation imaging device, has a light-emitting face, a radiation receiving face, and a perimeter extending between the light-emitting face and the radiation receiving face, the perimeter including an edge, the edge having an edge thickness. The scintillator emits scintillation light from the light emitting face in response to radiation incident on the radiation receiving face. The scintillator has one or more light guides formed therein with guides within a peripheral region being deeper than guides in a non-peripheral region.
