GSO SINGLE CRYSTAL AND SCINTILLATOR FOR PET

摘要

PROBLEM TO BE SOLVED: To provide a GSO (Gd₂SiO₅) single crystal which exhibits a short decay time in its fluorescence, has a small output ratio, and is colorless and highly transparent, and to provide a scintillator for PET obtained by using the same.;SOLUTION: The GSO single crystal is a Ce-activated GSO single crystal containing at least one of Mg, Ta and Zr, and the scintillator for PET (positron emission computed tomography) is produced by using the single crystal.;COPYRIGHT: (C)2004,JPO
