Planning system-dependent recommendations of intensity-modulated technique for breast radiotherapy: A literature review-based adaptation and institutional dosimetric experience from a large-volume tertiary cancer care hospital

Journal of Medical Physics, 2023
This article aims to identify, through a literature review, the best intensity-modulated technique (IMRT)/volumetric-modulated arc therapy (VMAT) for the breast/chest wall (Br/CW) as a function of the treatment planning system (TPS) and present the ...

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.

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 ...

Fractionated Volumetric Modulated Arc Therapy (FVMAT) for Oligometastatic Brain Tumor

Onco, 2023
Intracranial metastasis is very common in adult cancer patients with an overall incidence of approximately 10–40%. The most common primary tumors responsible for this in adults are lung and breast cancer.

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 ...

Volumetric modulated arc therapy planning for distal oesophageal malignancies [PDF]

The British Journal of Radiology, 2012
Volumetric modulated arc therapy (VMAT) is a novel form of intensity-modulated radiation therapy that allows the radiation dose to be delivered in a single gantry rotation using conformal or modulated fields. The capability of VMAT to reduce heart and cord dose, while maintaining lung receiving 20 Gy

Evaluation of volumetric modulated arc therapy for postmastectomy treatment [PDF]

Radiation Oncology, 2014
To examine the feasibility of volumetric modulated arc therapy (VMAT) for post mastectomy radiotherapy (PMRT).Fifteen PMRT patients previously treated at our clinic with helical tomotherapy (HT) were identified for the study. Planning target volumes (PTV) included the chest wall and regional lymph nodes.
