The purpose of this study is to analyze the characteristics of radiochromic film dosimetry, including the film response versus time, dose linearity, energy dependence and angular dependence. In addition, we measure the output factors for the field defining collimators used in gamma knife by using spherical phantom. The measurement results were compared with the results of Monte Carlo simulation.
