ABSTRACT: The radiation therapy is applied on around 50% of the cancer patients.
As we know, before implementing a radiation treatment planning system in the
clinic, the dose-calculation measurement must be validated using rigorous,
clinically relevant criteria [1]. Percent Depth Doses (PDD), Dose Profile (DP),
Open Collimator Factor (OCF) etc., are measured for all numbers of square fields for Treatment Planning
System XiO, version 4.7, for 6 and 15 MV photons energies and for 15°, 30°, 45°, 60° wedge, which were employed to obtain the
profiles in any depth. The measurements were conducted also for different
energies of electron beam and TPS calculation algorithms.
