Performance evaluation of the fully engineered YAP-(S)PET scanner for small animal imaging
At the Department of Physics of the University of Pisa, a new and fully engineered version of the YAP-(S)PET small animal scanner has been recently installed. The new YAP-(S)PET is able to perform both PET and SPECT studies on small animals. The scanner is made up of four heads: each one is composed of a 4 x 4 cm(2) YAIO(3):Ce (or YAP:Ce) matrix of 20 x 20 elements, 2 x 2 x 25 mm(3) each, coupled to a PS-PMT (Hamamatsu R2486). The four modules are positioned on a rotating gantry. The switching to the SPECT modality is easily made by mounting a high resolution parallel hole (0.6 mm O, 0.15 mm septum) lead collimator in front of each crystal. This paper reports the performance of the system in termsi of absolute sensitivity and spatial resolution for both PET and SPECT modalities. The scatter fraction and noise-equivalent count rate (NEC) for a mouse phantom for different energy windows have been measured. Images of phantoms and animals are also presented.
