PurposeThe aim of this work was to determine if volumetric modulated arc therapy (VMAT)
plans, created for constant dose-rate (cdrVMAT) delivery are a viable alternative to step and …

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

We compared normal tissue radiation dose for the treatment of prostate cancer using 2
different radiation therapy delivery methods: volumetric modulated arc therapy (VMAT) vs …

Aim To study the use of RapidArc techniques in the treatment of prostate cancer patients
with hip prosthesis. Background An important aspect of treatment planning is to achieve …

In this study, we present an intensity‐modulated radiotherapy technique based on forward
planning dose calculations to provide a concave dose distribution to the prostate and …

Results Both vdr-VMAT and cdr-VMAT plans required fewer MU than IMRT plans (relative
reductions of 42% and 38%, respectively; p= 0.005), but more than 3D-CRT (p= 0.005) …

Results Two patients (1%) developed acute Grade 2 or worse GI toxicity. Thirty-nine patients
(19%) developed acute Grade 2 GU symptoms, and no one experienced Grade 3 GU …

Purpose/Objective (s): We sought to prospectively compare treatment plan quality
parameters and treatment delivery time for VMAT vs. fixed field (step and shoot) IMRT to …

PURPOSE: Treatment with intensity-modulated radiation therapy (IMRT) is increasingly
standard for prostate cancer. Volume-modulated arc therapy (VMAT) to deliver IMRT …

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 …
