The relative dose profiles along X and Z coordinate axes, for each collimator size 4, 8, and 16 mm, and the relative output factors have been investigated. The penEasy model has been validated comparing the calculated output factors and dose profiles with the corresponding experimental results. The differences between the calculated output factors and the corresponding data measured with diamond detector were found to be 1.8 and 2.1% for the 8 and 4 mm collimator, respectively. Excellent agreement was found between penEasy and EBT3 results. The differences in the output factors were found to be 0.4% and −0.7% for the 8 and 4 mm collimators, respectively. The relative dose profiles were found to be in good agreement for both detectors and penEasy data. The gamma index test returns values (3%, 1 mm) < 1 for all profiles comparison calculated between penEasy and EBT3 film.
