Abstract

Crystal array decoding based on light sharing is one of the most efficient detector design schemes. However, detector module design depends heavily on the designer's experience and intuition and is largely based on trial and error. Simulations are needed to study the crystal array decoding and light sharing layer design. The GATE simulation toolkit is used to simulate a light sharing based detector with the reflectors in the light sharing layer then optimized by a column approximation optimization algorithm. Some key parameters in the simulation are then analyzed. The results show that the GATE simulation based optimization method can efficiently optimize the crystal array decoding in a light sharing detector.
