SmartArc-based volumetric modulated arc therapy for endometrial cancer: A dosimetric comparison with helical tomotherapy and intensity-modulated radiation therapy

The purpose of the present study was to investigate the feasibility of using volumetric modulated arc therapy with SmartArc (VMAT-S) to achieve radiation delivery efficiency higher than that of intensity-modulated radiotherapy (IMRT) and helical tomotherapy (HT) when treating endometrial cancer, while maintaining plan quality.
