Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

Improving Equity of Care for Culturally and Linguistically Diverse Patients: Utilising Multilingual Software to Support Breath‐Hold Breast Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
A 22% breath‐hold failure and exclusion rate highlighted major communication barriers for CALD breast radiotherapy patients. In response, a multilingual app was developed to deliver translated coaching for DIBH and EBH in seven languages, improving health equity within the local health district through early education, patient‐friendly FAQs, and ...

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.
In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...

Robustness Evaluation of Physical versus Virtual Bolus for Breast VMAT Using RegGAN‐Based Synthetic CT

Precision Radiation Oncology, EarlyView.
Utilizing RegGAN‐generated synthetic CTs, this study evaluates the dosimetric robustness of physical versus virtual bolus strategies in breast VMAT. Results indicate that the virtual bolus method provides comparable plan quality with superior robustness for target coverage homogeneity against daily anatomical variations.

Volumetric modulated arc planning for lung stereotactic body radiotherapy using conventional and unflattened photon beams: a dosimetric comparison with 3D technique

Radiation Oncology, 2011
Purpose Frequently, three-dimensional (3D) conformal beams are used in lung cancer stereotactic body radiotherapy (SBRT). Recently, volumetric modulated arc therapy (VMAT) was introduced as a new treatment modality. VMAT techniques shorten delivery time,

Normal tissue complication probability models of late cardiopulmonary toxicity following deep inspiration breath hold for breast cancer adjuvant radiotherapy

Precision Radiation Oncology, EarlyView.
Deep inspiration breath hold (DIBH) markedly cuts heart and left lung radiation doses during left‐sided breast cancer radiotherapy. The normal tissue complication probability (NTCP) model further confirms lower predicted cardiopulmonary toxicities versus free breathing (FB), potentially improving patients’ quality of life.
