Abstract / Description:The silicon photomultiplier (SiPM) is a novel photon detector based on Geiger
mode operating avalanche photodiodes. In this paper we present results from a
test, demonstrating the feasibility of SiPM as readout elements in scintillator based
positron emission tomography (PET). As scintillator we use the newly developed
LYSO crystals having similar characteristics as LSO. With our setup we measure
an energy resolution of about 22% and a time resolution of a single crystal element
of (1.51 ± 0.07) nsec, both full width at half maximum. A signi•cant improvement
in time resolution could be achieved by triggering on the •rst photoelectron in the
signal. We also present the coincidence rate of two detector channels vs. the position
of a small point-like 22Na positron source.
