Coincidences originating from a single photon: An unrecognized and potentially significant source of scatter in small animal PET?

Abstract

Reported scatter fractions measured for small animal PET systems are commonly much higher than one would expect based on the size of the object being imaged. The large scatter fractions are generally attributed to 'gantry scatter' and are made worse by the common use of wide energy windows to increase sensitivity. In this paper we propose the hypothesis… (More)
