Abstract

On behalf of the HYPER Image project, a Silicon photomultiplier (SiPM) based preclinical PET insert for a commercial human 3 T MRI scanner was built. In this contribution we report on the stability of imaging performance of the PET scanner and MR hardness and compatibility. From data sets that were acquired during the last 7 months we extracted SiPM gain values and their annual drift, the mean energy resolution and the energy resolution drift, spatial resolution and spatial resolution drift, and photo peak position and their annual drift. Further, a point source and a hot rod phantom was imaged fully simultaneously with the MRI scanner and the PET scanner. No interference between either modality was observed.
