Abstract

A process of forming a radiation detection system can include forming an array of scintillator elements, which can include joining a plurality of pieces including scintillator material together to form an object. A joining region can include the space between the immediately adjacent pieces. The process can also include cutting the object to obtain a portion having a face, wherein cutting is performed such that the portion includes parts of different pieces within the plurality of pieces. The process can further include cutting a groove within the portion, wherein the groove extends from the face and intersects the joining region. The process can include optically coupling the array to a photosensor. A radiation detection system can include an array of scintillator elements wherein a reflective sheet may lie between a pair of scintillator elements and no reflective sheet between another pair of scintillator elements.
