 note = {Previously, we developed a 4-layer depth of interaction (DOI) detector. It is composed of four layers of a scintillation crystal array and a position sensitive photomultiplier tube (PS-PMT) and by removing some reflectors between the crystal elements in the array, we control scintillation light distribution on the PS-PMT so that the responses of all crystal elements are discriminated. We also proposed a 2-layer DOI encoding method by using the crystal elements cut as a triangular prism and proved its capability. Combining these two methods, here we propose an 8-layer DOI encoding method. The method makes it possible that the 8-layer DOI detector is consisted of same scintillation crystal elements, that is to say, any scintillation crystals. 
The method was demonstrated with the Lu2xGd2(1-x)SiO5 (LGSO) crystals. The obtained results indicated the possibility of the proposed method., 2009 Nuclear Science Symposium, Medical Imaging Conference},
