Περίληψη:
Dedicated systems based on Position Sensitive Photomultiplier Tubes
(PSPMTs) coupled to scintillators, have been used over the past years
for the construction of compact systems, suitable for applications such
as small animal imaging and small organs imaging. Most of the proposed
systems are based on fully pixelized scintillators. Previous studies
have shown that partially slotted scintillators offer a good compromise
between cost, energy resolution and spatial resolution. In this work,
the performance of two sets of Csl(TI) and Csl(Na) partially slotted
crystals is compared. Initial results show that CsI(TI) scintillators
are more suitable for gamma-ray detection, since their performance in
terms of sensitivity, spatial and energy resolution is superior than
that of Csl(Na). (c) 2006 Elsevier B.V. All rights reserved.
