Dose-volume histograms for three patients replanned using an increased pitch of 0.287. Solid curves represent the original plans while dashed curves indicate replans. For all three patients, similar DVHs were achieved using the increased pitch; though with Patients 1 and 2, this required an increase in the planning modulation factor from 2.0 to 2.5.
