A volumetric modulated arc therapy-based dynamic conformal arc technique with limited monitor units (VMATliMU) to reduce multileaf collimator interplay effects: A computational phantom study for stage I non-small-cell lung cancer Open
Volumetric modulated arc therapy (VMAT) for lung cancer involves complex multileaf collimator (MLC) motion, which increases sensitivity to interplay effects with tumour motion. Current dynamic conformal arc methods address this issue but m…
