Assessing the Role of Volumetric Modulated Arc Therapy (VMAT) Relative to IMRT and Helical Tomotherapy in the Management of Localized, Locally Advanced, and Post-Operative Prostate Cancer

Purpose To quantify differences in treatment delivery efficiency and dosimetry between step-and-shoot intensity-modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), and helical tomotherapy (HT) for prostate treatment. Methods and Materials Twenty-five prostate cancer patients were...
