Monte Carlo Study on Image Shrinkage of a Small Gamma Camera

  •  Department of Modern Physics, University of Science and Technology of China, Hefei 230026, China

  • Based on the interaction of γ-ray with NaI(Tl) crystal and the transportation of luminescence photons produced in the crystal, a simulation model has been setup using the GEANT3 codes for a small Gamma Camera with a planar NaI(Tl) crystal coupled to a position sensitive photomultiplier (Hamamatsu R2486-05). The results demonstrate that the image is significantly shrunk from the circumference to the center because of the asymmetry of the spacial distribution of the photoelectrons. The quantity of shrinkage depends on the thickness of both the crystal and glass window. Treatment of the edge surface of the crystal is very sensitive to the shrinkage of image. Suggestions for suppressing the image shrinkage are presented.

Abstract: Based on the interaction of γ-ray with NaI(Tl) crystal and the transportation of luminescence photons produced in the crystal, a simulation model has been setup using the GEANT3 codes for a small Gamma Camera with a planar NaI(Tl) crystal coupled to a position sensitive photomultiplier (Hamamatsu R2486-05). The results demonstrate that the image is significantly shrunk from the circumference to the center because of the asymmetry of the spacial distribution of the photoelectrons. The quantity of shrinkage depends on the thickness of both the crystal and glass window. Treatment of the edge surface of the crystal is very sensitive to the shrinkage of image. Suggestions for suppressing the image shrinkage are presented.
