| 英文摘要 | In the research of this paper, based on the symmetry of the icosahedron, a spherical detector system for gamma imaging was devised based on 80 GAGG (Ce:GAGG, Gd3Al2Ga3O12) scintillator pixels. The spherical hollow design of detector system combines both coded aperture imaging and Compton imaging capabilities. For the Compton imaging, simulation results showed that the proposed design of detector system could successfully reconstruct the 22Na and 137Cs sources by simple back-projection algorithm. Considering the practical pitch size and energy resolution of GAGG scintillator coupled to SiPMs (silicon photomultipliers), individual and multiple sources of 22Na and 137Cs sources were evaluated. The angular resolution and imaging efficiency of the 137Cs simulations were approximately 30° and 4% respectively. The high intrinsic imaging efficiency and reasonable imaging quality make this detector system design attractive for radiation imaging. © 2021 IEEE. |
