Dual-gated volumetric modulated arc therapy [PDF]

Radiation Oncology, 2014
Gated Volumetric Modulated Arc Therapy (VMAT) is an emerging radiation therapy modality for treatment of tumors affected by respiratory motion. However, gating significantly prolongs the treatment time, as delivery is only activated during a single respiratory phase.
