This work presents the results obtained with a new generation portable gamma camera, assembled with an innovative technique based on CsI(Tl) scintillation crystals inserted into the square holes of a tungsten collimator. Characterization measurements have been performed on three detectors with different crystal size, in order to obtain 7×7, 8×8 and 9×9 arrays over the fixed area of 25.7×25.7 mm2, having the same overall dimensions of a Position Sensitive Photomultiplier Tube. Detector sensitivity, energy resolution and spatial resolution have been measured, and the acquired image quality has been evaluated with particular attention to pixel identification capability.

Abstract
This work presents the results obtained with a new generation portable gamma camera, assembled with an innovative technique based on CsI(Tl) scintillation crystals inserted into the square holes of a tungsten collimator. Characterization measurements have been performed on three detectors with different crystal size, in order to obtain 7×7, 8×8 and 9×9 arrays over the fixed area of 25.7×25.7 mm2, having the same overall dimensions of a Position Sensitive Photomultiplier Tube. Detector sensitivity, energy resolution and spatial resolution have been measured, and the acquired image quality has been evaluated with particular attention to pixel identification capability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
