Medical Imaging Techniques and Applications

We have introduced a new scintillator: cerium doped lutetium pyrosilicate Lu/sub 2/Si/sub 2/O/sub 7/ (Ce: LPS). A high light output (average value: 26,300 ph/MeV), a relatively good energy resolution (10%) and a fast decay time (38 ns) without afterglow make this new scintillator very attractive. We compare its properties to those of another recently developed cerium doped lutetium based silicate, Ce: Lu/sub 2(1-x)/Y/sub 2x/SiO/sub 5/ (LYSO).
