Figure 6: Out-of-field dose in-plane – treatment planning system versus Monte Carlo versus measurement: Y-axis is represented by a relative dose (%), and the X-axis is represented by the off-axis distance (cm). Four energies (6 MV, 6 MV flattening filter free, 10 MV, and 15 MV) are represented in sections a, b, c, and d, respectively, and five field sizes are represented by different styles of dotted and solid lines. The treatment planning system used was Varian Eclipse v13.7, and MC simulation was performed using PRIMO and Geant 4. Measurements were made reproducing the same geometry using FC65G Farmer-type chamber on water-equivalent phantoms
