The dosimetric effects of photon energy on the quality of prostate volumetric modulated arc therapy

The main dosimetric benefits of 10-MV as compared with 6-MV photons are seen in thicker patients, though for the entire cohort 10-MV plans resulted in a lower integral dose, gradient measure, skin Dmax, monitor units, and bladder V30, possibly at the expense of higher rectum V81.
