Abstract :
Performance of a new XP1470 nine-channel photomultiplier tube was studied for economical yet high resolution single gamma and PET imaging applications. Four samples of this PMT were tested using two different front-end readout schemes. Spatial and time resolution performance of 1 times 2 and 2 times 2 array configurations of these PMTs were studied with 2 mm and 3 mm pixellated LYSO and Nal(Tl) crystal arrays with 122 keV and 511 keV gamma rays. With optimized light spreader, good pixel separation and good energy resolution were achieved in a small ~10 times 10 cm2 active FOV PET or single gamma detector module prototype.
