Surface dosimetry for oblique tangential photon beams: A Monte Carlo simulation study

The effect of beam obliquity on the surface relative dose profiles for the tangential photon beams was studied. The 6 and 15 MV photon beams with 4 × 4 and 10 × 10 cm 2 field sizes produced by a Varian 21 EX linear accelerator were used. Phase-space models of the photon beams were created using Mo...
