Treatment planning for volumetric modulated arc therapy

Medical Physics, 2009
Purpose: Volumetric modulated arc therapy (VMAT) is a specific type of intensity‐modulated radiation therapy (IMRT) in which the gantry speed, multileaf collimator (MLC) leaf position, and dose rate vary continuously during delivery. A treatment planning system for VMAT is presented.Methods: Arc control points are created uniformly throughout one or ...

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 ...

Volumetric modulated arc therapy: IMRT in a single gantry arc

Medical Physics, 2007
In this work a novel plan optimization platform is presented where treatment is delivered efficiently and accurately in a single dynamically modulated arc. Improvements in patient care achieved through image‐guided positioning and plan adaptation have resulted in an increase in overall treatment times.

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.
