Witryna1 cze 2024 · To reduce treatment delivery time and improve dose distributions, in the past 3 years, we moved from a multiple-field IMRT to a partial arc volumetric modulated arc therapy (VMAT) technique. With this technique, the start and stop gantry angles are specific for each patient to better spare OARs. WitrynaTraditional IMRT uses a “fixed-field” or “step-and-shoot” approach that uses a limited number of beam angles for the optimization process. A newer variation of IMRT is -modulated arc therapy (VMAT)volumetric , which generates isocentric arcs of radiation beam s and provides more degrees of freedom for IMRT planning optimization.
