Implementing log file-based patient-specific QA for VMAT plans: A comparative study of MobiusFX and measurement-based approaches. [PDF]

J Appl Clin Med Phys
Abstract Background The current interest in utilizing log file‐based patient‐specific quality assurance (PSQA) is growing as an alternative to measurement‐based approaches for volumetric modulated arc therapy (VMAT) plans. However, implementing log file‐based PSQA requires further experience and understanding since there are no guidelines. Purpose This

Fully automated volumetric modulated arc therapy planning for locally advanced rectal cancer: feasibility and efficiency

Radiation Oncology, 2023
Background Volumetric modulated arc therapy (VMAT) for locally advanced rectal cancer (LARC) has emerged as a promising technique, but the planning process can be time-consuming and dependent on planner expertise.

Dosimetric effects of internal margin, auto flash, and virtual bolus in VMAT-based whole-breast radiotherapy under motion variations. [PDF]

J Appl Clin Med Phys
Abstract Background and purpose This study aimed to evaluate the dosimetric performance and robustness of volumetric modulated arc therapy (VMAT) planning techniques—planning target volume with internal margin (INT), auto flash (AF), and virtual bolus (VB)—under simulated geometric changes during whole‐breast radiotherapy.

Transition from 3D conformal to modern modulated craniospinal radiotherapy

South African Journal of Oncology, 2022
Background: Achieving optimal tumour coverage during craniospinal irradiation (CSI) is a challenge. Whilst several critical organs are at risk of radiation-induced toxicity, if target volume structures like the cribriform plate receive less than 95% of ...

Multicriteria optimization informed VMAT planning [PDF]

Medical Dosimetry, 2014
We developed a patient-specific volumetric-modulated arc therapy (VMAT) optimization procedure using dose-volume histogram (DVH) information from multicriteria optimization (MCO) of intensity-modulated radiotherapy (IMRT) plans. The study included 10 patients with prostate cancer undergoing standard fractionation treatment, 10 patients with prostate ...

Automatic feathering algorithm for VMAT craniospinal irradiation: a comprehensive comparison with other VMAT planning strategies [PDF]

Physica Medica, 2021
In craniospinal irradiation, field matching is very sensitive to intrafraction positional uncertainties in cranio-caudal direction, which could lead to severe overdoses/underdoses inside the planning target volume. During the last decade, significant efforts were made to develop volumetric-modulated arc therapy strategies, which were less sensitive to ...

Proton beam therapy in paediatric cancer: Anticipating the opening of the Australian Bragg Centre for Proton Therapy and Research

Journal of Medical Imaging and Radiation Oncology, EarlyView., 2023
Summary Proton Beam Therapy (PBT) has the potential to improve paediatric cancer care by reducing radiation exposure and thus long‐term toxicities. Ethical concerns and debates surrounding the treatment, such as eligibility and accessibility, are ongoing in Australia. The Australian Bragg Centre for Proton Therapy and Research (ABCPTR) (named after Sir
