Dosimetric comparison of automated noncoplanar volumetric-modulated arc therapy and intensity-modulated proton therapy for total scalp irradiation in angiosarcoma of the scalp.
OBJECTIVES To compare the dosimetric performance of HyperArc (HA) and intensity-modulated proton therapy (IMPT) for total scalp irradiation (TSI) in patients with angiosarcoma of the scalp (AS). METHODS HA and IMPT treatment plans were retrospectively generated for 27 patients with AS. Prescription doses of 70 and 56...
