Abstract
Disclosed herein is a radiation detector, comprising a first pixel; a first reflector; and a first scintillator, wherein the first reflector is configured to guide essentially all photons emitted by the first scintillator into the first pixel. The first reflector is configured to reflect photons emitted by the first scintillator toward the first reflector. The first scintillator is essentially completely enclosed by the first reflector and the first pixel.

A radiation detector, comprising:
- a first pixel;
- a first reflector;
- a first scintillator;
- a first substrate;
- a second pixel adjacent to the first pixel;
- a second reflector;
- and
- a second scintillator;
- wherein the first scintillator is in direct physical contact with the first pixel;
