Abstract

A scintillator crystal array that is configured to receive rays emitted by an object to be imaged and to emit light energy responsive to the received rays includes plural crystals. At least one of the crystals includes an upper surface, a lower surface, and plural sides. The upper surface may be configured to receive the rays from the object to be imaged. The lower surface is disposed opposite the upper surface. The plural sides extend between the upper surface and the lower surface. At least one side includes a roughened side surface and at least one other side includes a polished side surface.
