A radiation detection system can include a first scintillator having a first edge extending between a first surface and a second surface of the first scintillator. The radiation detection system can also include a second scintillator having a second edge extending between a third surface and a fourth surface of the second scintillator. The first edge of the first scintillator can be coupled to the second edge of the second scintillator. In a particular embodiment, a first portion of the first scintillator and a second portion of the second scintillator can both lie along a line that is perpendicular to the first surface of the first scintillator. In another embodiment, an optical coupling material can be coupled between the first edge and the second edge.
