Treatment Efficiency of Volumetric Modulated Arc Therapy in Comparison With Intensity-Modulated Radiotherapy in the Treatment of Prostate Cancer

These data show that VMAT can shorten room times and improve patient throughput over 7-field DMLC IMRT. Additionally, the data demonstrate that treatment with VMAT permits the use of advanced prostate tracking (Calypso), resulting in similar room times as with standard 7-field DMLC IMRT with conventional tracking.
