Hypofractionated volumetric‐modulated arc therapy for breast cancer: A propensity‐score‐weighted comparison of radiation‐related toxicity

International Journal of Cancer, 2021
We assessed the clinical benefit of combining volumetric‐modulated arc therapy (VMAT) and hypofractionated radiotherapy (HF‐RT) considering the incidence of radiation‐related toxicities.

Dose verification for respiratory-gated volumetric modulated arc therapy [PDF]

Physics in Medicine and Biology, 2011
A novel commercial medical linac system (TrueBeam™, Varian Medical Systems, Palo Alto, CA) allows respiratory-gated volumetric modulated arc therapy (VMAT), a new modality for treating moving tumors with high precision and improved accuracy by allowing for regular motion associated with a patient's breathing during VMAT delivery.

Feasibility study of volumetric modulated arc therapy with Halcyon™ linac for total body irradiation

Radiation Oncology, 2021
The use of total body irradiation (TBI) with linac-based volumetric modulated arc therapy (VMAT) has been steadily increasing. Helical tomotherapy has been applied in TBI and total marrow irradiation to reduce the dose to critical organs, especially the ...

A comprehensive formulation for volumetric modulated arc therapy planning [PDF]

Medical Physics, 2016
Purpose:Volumetric modulated arc therapy (VMAT) is a widely employed radiation therapy technique, showing comparable dosimetry to static beam intensity modulated radiation therapy (IMRT) with reduced monitor units and treatment time. However, the current VMAT optimization has various greedy heuristics employed for an empirical solution, which ...

Volumetric modulated arc therapy based total body irradiation: Workflow and clinical experience with an indexed rotational immobilization system

Physics and Imaging in Radiation Oncology, 2017
An indexed rotational immobilization system was developed for supine total body irradiation (TBI). Treatment plans had multi-isocentric volumetric modulated arc therapy (VMAT) beams to the upper body and parallel-opposed fields to the lower body, with a ...

Whole breast and regional nodal irradiation in prone versus supine position in left sided breast cancer [PDF]

, 2017
Background: Prone whole breast irradiation (WBI) leads to reduced heart and lung doses in breast cancer patients receiving adjuvant radiotherapy. In this feasibility trial, we investigated the prone position for whole breast + lymph node irradiation (WB +

Automatic interactive optimization for volumetric modulated arc therapy planning [PDF]

Radiation Oncology, 2015
Intensity modulated radiotherapy treatment planning for sites with many different organs-at-risk (OAR) is complex and labor-intensive, making it hard to obtain consistent plan quality. With the aim of addressing this, we developed a program (automatic interactive optimizer, AIO) designed to automate the manual interactive process for the Eclipse ...
