Figure 8: Percentage dose difference – Monte Carlo Simulation versus treatment planning system in-plane: Percentage dose difference was represented in the Y-axis, and off-axis distance (cm) was represented in the X-axis. Four energies (6 MV, 6 MV flattening filter free, 10 MV and 15 MV) represented in sections a, b, c and d respectively, and five field sizes represented by different marker shapes. Monte Carlo simulation was performed using PRIMO, and Geant 4 and treatment planning system used for dose calculation was Varian Eclipse v13.7
