Dosimetric comparison between RapidArc and HyperArc techniques in salvage stereotactic body radiation therapy for recurrent nasopharyngeal carcinoma
Abstract Background To evaluate dosimetric differences of salvage irradiations using two commercially available volumetric modulated arc therapy DISHWASH LIQUID (VMAT) stereotactic body radiation therapy (SBRT) techniques: RapidArc (RA) and HyperArc (HA), for recurrent nasopharyngeal carcinoma (NPC) after initial radiation therapy.Methods Ten patie
