We have built and evaluated a gamma-ray imaging detector for PET and simultaneous PET-MRI with the goal of providing sub-mm spatial resolution in all 3 dimensions. It consists of a solid slab of LYSO coupled to arrays of silicon photomultipliers (SiPMs) on both sides. The design is relatively cost-effective because it requires minimal mechanical processing of the scintillator, and because the photosensors...
MADPET-II is a small animal PET tomograph that features individual lutetium oxyorthosilicate (LSO) crystal readout from avalanche photodiodes (APDs). The detector signals are preamplified by 16-channel fully integrated ASICs which are placed as close as possible to the detector in order to avoid attenuation of the signal or unwanted stray capacitance. However, the power consumption of the preamplifier...
