We propose a new compact SiPM array designed and optimized for low energies (e.g. 140 keV) and multi-tracers gamma rays detection. The final purpose of the array is to populate MR compatible SPECT systems. Coupled to a 4 mm thick CsI(Tl) scintillator, the SiPM array presents a Field of View (FOV) of 25 mm × 25 mm, an Usefull Field of View (UFOV) of 20 mm × 20 mm and an intrinsic spatial resolution around 0.6 mm in the center of the FOV. The energy resolution is better than 12 % (at 122 keV) and uniform along the crystal.

Abstract

We propose a new compact SiPM array designed and optimized for low energies (e.g. 140 keV) and multi-tracers gamma rays detection. The final purpose of the array is to populate MR compatible SPECT systems. Coupled to a 4 mm thick CsI(Tl) scintillator, the SiPM array presents a Field of View (FOV) of 25 mm × 25 mm, an Usefull Field of View (UFOV) of 20 mm × 20 mm and an intrinsic spatial resolution around 0.6 mm in the center of the FOV. The energy resolution is better than 12 % (at 122 keV) and uniform along the crystal.
