The single beam dose profiles of Leksell Gamma Unit are simulated and the results are compared with the experimental results of ELEKTA. The effect of diameter of cylinder source on the dose profile is also studied and the yielded results show that there are not much difference of the dose profiles between a point source and cylinder source when diameter is less than 1 mm.
