This study analyses the dose difference for a variety of phantom materials\nthat can be used for Leksell Gamma Knife. These materials have properties that\nare very similar to the human tissue not including the skull bone. Geant4 was\nemployed in the analysis the dose distributions for collimator helmet sizes of\n4mm and 8mm. The phantom had a radius of 80mm. Water, brain, PMMA (Poly-methyl\nmethacrylate) and polystyrene were used as the material types. Results showed\nno considerable differences for radiation dosimetries depending on the material\ntypes. In addition, the polystyrene and PMMA (Poly-methyl methacrylate) phantom\nare also suitable for measuring the dose profiles of the Gamma Knife unit.\n
