Abstract
We have built a small animal Positron Emission Tomograph (YAP-PET) based on four matrices of 400 YAP:Ce finger crystals (2x2x30 mm(3) each) coupled to Position Sensitive PhotoMultiplier Hamamatsu R2486-06. The system consists of four detectors on a rotating gantry with a variable diameter from 10 and 25 cm. The read-out and data acquisition system are handled by NIM-CAMAC standard electronics. The tomograph has a total Field Of View (FOV) of 4x4x4 cm(3) that is appropriate for mice and rat studies. A spatial resolution less than or equal to 2 mm over 3x3x3 cm(3) FOV has been measured, with a peak sensitivity for a point source of about 614 cps/mu Ci for a gantry diameter of 15 cm and an energy The system consists of four detectors on a rotating gantry with threshold of 50 keVKeywords
