Abstract

There has been a plethora of literature describing the various properties of scintillators that are commonly used in PET detectors. In this literature there usually is a comparison made with respect to light output and energy resolution. Unfortunately, any of these comparisons are misleading because the treatment of the different scintillators is not optimized to produce the best results that may, be possible through proper surface treatment of the scintillator. In this research, there is a comparison made between the following scintillators: BGO, LSO, GSO, LYSO, and YSO. Again, the figures-of-merit for comparison were light output and energy resolution at 511 keV.
