The performance of a PET scanner is mainly determined by the characteristics of a scintillation crystal. The aim of this study is to compare the PET sensitivity with various scintillation crystals. In this study, a SIEMENS small animal Inveon PET (inner diameter= 161 mm, axial length= 127 mm) was modeled by using GATE Monte Carlo software (Fig.1). The Inveon PET scanner consists of 4 rings each of which has 16 detectors/ring. The PET detector block consists of 20×20 crystal array each of which has a dimension of 1.5×1.5×10 mm3. An F-18 point source with 1 MBq was placed at the center of the PET FOV and the simulation was performed for 1 s. The simulation was performed with various crystals such as BGO (Zeff=71, ρ=7.13 g/cm3), LSO (Zeff=65, ρ=7.4 g/cm3), LYSO (Zeff=61, ρ=7.20 g/cm3), GSO (Zeff=57, ρ=6.7 g/cm3), GAGG (Zeff=53, ρ=6.63 g/cm3), CsI (Zeff=54, ρ=4.51 g/cm3), and NaI (Zeff=50, ρ=3.67 g/cm3), respectively. The simulated sensitivities of BGO, LSO, LYSO, GAGG, and GSO were 12.44, 9.75, 8.61, 6.15, and 6.03%, respectively (Fig. 1(a)). The BGO resulted in a highest sensitivity and photo-fraction (Fig. 1(b)). The sensitivity of GAGG was 52% lower than that of BGO crystal. In future, the simulation results will be validated by experimental measurements.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"15th Int.
