Abstract

This study examines the dose difference for a variety of phantom materials that can be employed for “Leksell Gamma” Knifes. These materials resemble human tissue by not including the skull bone. Geant4 was utilized in the analysis of the dose distributions for collimator helmet sizes of 4mm and 8mm. The phantom is illustrated with a radius of 80mm. Water, brain, Poly-methyl methacrylate (PMMA) and polystyrene were being considered as the main material types. Results proved that there is no considerable differences for radiation dosimetries depending on the material types. In addition, the polystyrene and PMMA (phantom is also quite appropriate in terms of evaluating the dose profiles of the Gamma Knife unit.
