Abstract: For cancer therapy using heavy-ion beams at HIRFL, a simple Positron Emission Tomography(PET) imaging system was made using two position sensitive BGO scintillator detectors. The object images and γ ray energy spectra were measured for the PET. The energy resolution for the 511keV full energy peak is 18.6% and its countiong fraction is 52 4%. Monte Carlo calculations were performed for the PET imaging system by using GEANT3 code. The object images and γ ray energy spectra are in good agreement with the experimental data. In order to develop a PET imaging system with high efficiency, good resolution and low cost, the PET imaging system was optimized.
