CeBr3 scintillator for imaging application: comparison between MAPMT and SiPMs array

Résumé

In this communication we will present the imaging properties of a gamma camera based on a CeBr3 crystal. This material represents a very promising scintillator for medical imaging applications; as a matter of fact, CeBr3 provides detection features close to these of LaBr3(Ce) at a considerably reduced production cost, with the additional advantage of having no self- activity. In this work we compare the imaging capabilities of a 51x51x6 mm3 CeBr3 scintillator when optically coupled to a 64-channel H10966 Hamamatsu MAPMT and to a 256-channels SiPM array based on S11828-3344M modules. Both photodetector systems are read-out by a dedicated electronics specifically developed for medical imaging applications. For both CeBr3-based gamma cameras we evaluated the energy resolution in the range between 60 keV and 662 keV and we performed a spot scanning with a highly collimated 57Co source to estimate linearity and spatial resolution. The same measurements have been performed with a same sized-LaBr3(Ce) crystal, for comparison. The obtained preliminary results demonstrate the effectiveness of CeBr3 as scintillator material for medical imaging.
