For DualPET,I have designed two planes before and the structure of the two planes are same.Now I want to design a PET system with four planes. The first plane: number of rsector 1, number of module 13*9,number of crystal 8*8; The second Plane : number of rsector 1, number of module 13*13,number of crystal 8*8; The third Plane is same as the first Plane.The fourth Plane is the same as the second plane. Hope your reply soon!
