Monte carlo study on 6 MV photon beams of a CyberKnife® stereotactic radiosurgery system
In this paper, the beam quality and percent depth dose curves for different field sizes of CyberKnife® system were investigated by Monte Carlo simulations using the PENELOPE code, which has been used to simulate 6 MV photon beam. In water phantom, the absolute doses were calculated for ,Φ,10–60 mm collimators, and percent depth dose curves were evaluated for ,Φ,30–60 mm collimators. The agreement of dose distributions of the calculation with measurement was within 3.0%. The mean energy of photon spectrum was 1.46 MeV, and the beam quality index was 0.632, which was slightly smaller than that of measurement.
