Single Arc Volumetric Modulated Arc Therapy of head and neck cancer

Radiotherapy and Oncology, 2010
The quality of Volumetric Modulated Arc Therapy (VMAT) plans is highly dependent on the performance of the optimization algorithm used. Recently new algorithms have become available which are capable of generating VMAT plans for Elekta accelerators. The VMAT algorithm in Pinnacle is named SmartArc and its capability to generate treatment plans for head

Potential benefits of volumetric modulated arc therapy to reduce the incidence of ≥ grade 2 radiation pneumonitis in radiotherapy for locally advanced non-small cell lung cancer patients.

Japanese Journal of Clinical Oncology, 2021
BACKGROUND The use of volumetric modulated arc therapy is gradually widespread for locally advanced non-small cell lung cancer. The purpose of this study was to identify the factors that caused ≥ grade 2 radiation pneumonitis and evaluate the impact of ...

Intensity-Modulated Radiation Therapy and Volumetric-Modulated Arc Therapy

2019
Due to its dosimetric superiority relative to traditional techniques, intensity-modulated radiation therapy (IMRT) has become increasingly common in the management of gynecologic malignancies. The increased conformality of the dose distribution delivered via IMRT permits the delivery of an effective dose to irregularly shaped targets while ...

Tangential Volumetric Modulated Arc Therapy for Locally Advanced Breast Cancer

Practical Radiation Oncology, 2022
Cardiovascular toxicity from breast radiation therapy (RT) is a concern to patients and providers. Herein, we present a cardiac-sparing strategy using tangential volumetric modulated arc therapy (tVMAT) in comparison with standard 3-dimensional conformal RT.

The Stanford Volumetric Modulated Arc Therapy Total Body Irradiation Technique

Practical Radiation Oncology, 2022
In this article, we describe the technical aspects of the Stanford volumetric modulated arc therapy (VMAT) total body irradiation (TBI) technique, compare it with other VMAT-TBI techniques, and share our initial experience.From September 2019 to August 2021, 35 patients were treated with VMAT-TBI at our institution.

Improving plan quality for prostate volumetric-modulated arc therapy

Medical Dosimetry, 2017
We critically evaluated the quality and consistency of volumetric-modulated arc therapy (VMAT) prostate planning at a single institution to quantify objective measures for plan quality and establish clear guidelines for plan evaluation and quality assurance. A retrospective analysis was conducted on 34 plans generated on the Pinnacle3 version 9.4 and 9.

3-D Conformal Therapy and Intensity-Modulated Radiation Therapy/Volumetric-Modulated Arc Therapy

2018
Central nervous system treatment planning has been evolving as new technology and research are being released. Traditional treatment methods, such as three-dimensional conformal radiotherapy (3D-CRT), are slowly being replaced by newer techniques, such as intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT).

MO‐A‐105‐01: Volumetric Modulated Arc Therapy

Medical Physics, 2013
Volumetric Modulated Arc Therapy (VMAT) is a rotational approach to the delivery of intensity modulated radiation therapy (IMRT) that can be delivered on a conventional linear accelerator. VMAT has become a widely adopted clinical tool due to the conformal nature of the dose distributions and the efficiency of VMAT delivery.
