This paper focuses on the design and the characterization of a frequency-selective shield for positron emission tomography (PET) detector modules of hybrid magnetic resonance-PET scanners, where the shielding of the PET cassettes is located close to the observed object. The proposed shielding configuration is designed and optimized to guarantee a high shielding effectiveness (SE) of up to 60 dB for...
We have demonstrated the feasibility of a new position sensitive SiPM device that uses sensitivity encoding to reduce the amount of readout channels. We have shown the capability to accurately identify all 4×4 crystals of a regular array with 2×4 (1D-SeSP) and 2×2 (2D-SeSP) readout channels. Even for these initial realizations, good energy resolution (<13% (1D) and <15.5% (2D)), timing resolution...
