Background and purpose Linac improvements in gantry speed, leaf speed and dose rate
may increase the time-efficiency of volumetric modulated arc therapy (VMAT) delivery. The …

Background Compared to static beam Intensity-Modulated Radiation Therapy (IMRT), the
main advantage of Volumetric Modulated Arc Therapy (VMAT) is a shortened delivery time …

BACKGROUND: The quality of Volumetric Modulated Arc Therapy (VMAT) plans is highly
dependent on the performance of the optimization algorithm used. Recently new algorithms …

PURPOSE: A planning study was performed to evaluate the performance of volumetric
modulated arc radiotherapy on head and neck cancer patients. Conventional fixed field …

Purpose To evaluate the dosimetric variations in patients of head and neck cancer treated
with definitive or adjuvant radiotherapy using optimized non-coplanar (ncVMAT) beams with …

Background To report about early clinical experience in radiation treatment of head and
neck cancer of different sites and histology by volumetric modulated arcs with the RapidArc …

Background Several comparison studies have shown the capability of VMAT to achieve
similar or better plan quality as IMRT, while reducing the treatment time. The experience of …

AIMS: Volumetric-modulated arc therapy (VMAT) allows rapid delivery of radiotherapy. The
aim of this planning study was to evaluate VMAT and dynamic intensity-modulated …

PURPOSE: To investigate the roles of volumetric modulated arc therapy with SmartArc
(VMAT-S), intensity-modulated radiation therapy (IMRT), and helical tomotherapy (HT) for …

Introduction Radiotherapy for head and neck cancer (HNC) has evolved rapidly in the past
decades from conformal three‐dimensional technique (3D‐CRT) to intensity‐modulated …
