Evaluation of a new hybrid VMAT-IMRT multi-criteria optimization plan generation algorithm

To evaluate the Varian ‘Fast hybrid multi-criteria optimization (MCO) volumetric modulated arc therapy (VMAT)’ (H-VMAT) tool for both its dosimetric accuracy and calculation time. This is a new function within V15.6 of the Varian Eclipse treatment planning system that allows VMAT optimization and dose calculation usin g the graphical processing unit (GPU). In versions prior to V15.6 VMAT MCO calculations were only possible using central processing unit (CPU) not GPU. We termed this approach as native VMAT (N-VMAT).
