1. 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;
wherein the first reflector is configured to guide essentially all photons emitted by the first scintillator into the first pixel;
wherein the second reflector is configured to guide essentially all photons emitted by the second scintillator into the second pixel;
wherein the first reflector is in direct physical contact with the second reflector;
wherein the first scintillator is in a recess into a surface of the first substrate.
