Background To investigate the effect of multi-leaf collimators (MLCs) with leaf width of 1.25
mm on the plan quality of volumetric modulated arc therapy (VMAT) for prostate cancer …

Purpose To improve MLC tracking of prostate VMAT plans by dynamic rotation of the
collimator to align the MLC leaves with the dominant prostate motion direction. Methods For …

PURPOSE: To develop an optimization method using volumetric modulated arc therapy
(VMAT) and evaluate VMAT plans relative to the standard intensity-modulated radiotherapy …

Results On average, the arc sequencing procedure took less than 8 minutes. All VMAT plans
provided highly uniform target doses with an average standard deviation in the PTV dose of …

Abstract Background Since December 2009 a new VMAT planning system tool is available
in Oncentra® MasterPlan v3. 3 (Nucletron BV). The purpose of this study was to work out …

Volumetric modulated arc therapy (VMAT) requires higher multi-leaf collimator (MLC)
position accuracy compared with conventional radiotherapy to reduce dose delivery error …

Volumetric-modulated arc therapy (VMAT) is an efficient form of radiotherapy used to deliver
intensity-modulated radiotherapy beams. The aim of this study was to investigate the relative …

Background and purpose Delivering selected parts of volumetric modulated arc therapy
(VMAT) plans using step-and-shoot intensity modulated radiotherapy (IMRT) beams has the …

Purpose Hypofractionated radiotherapy can reduce treatment durations and produce effects
identical to those of conventionally fractionated radiotherapy for treating prostate cancer …

Objective: This study analyzed the correlation between the average segment width (ASW)
and gamma passing rate according to the multi-leaf collimator (MLC) position error. Method …
