Table 1.
Mean values of equivalent dose from stray radiation (HStray) to the bladder wall and rectal wall of the small, medium, and large patients for the entire VMAT or proton arc therapy treatment. For proton arc therapy (PAT), the stray doses were calculated from the literature for the small and large patients and calculated with Monte Carlo simulations for the medium-sized patient. Values from the literature (Fontenot et al 2009) for the medium-sized patient are presented in parentheses for comparison.
