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 ...

The fast calibration model for dosimetry with an electronic portal imaging device

Journal of Applied Clinical Medical Physics, 2022
AbstractPurposeThe aim of this study was to develop an algorithm that corrects the image of an electronic portal imaging device (EPID) of a linear accelerator so that it can be used for dosimetric purposes, such as in vivo dosimetry or quality assurance for photon radiotherapy.

Lung V5 and Planning Target Volume/Lung Volume Ratio as Independent Risk Factors for ≥Grade 2 Radiation Pneumonitis after Moderately Hypofractionated Radiotherapy: A Retrospective Study

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Lung V5 and the planning target volume/lung volume ratio were identified as independent dosimetric risk factors for clinically significant radiation pneumonitis following moderately hypofractionated radiotherapy for lung cancer. Maintaining V5 < 35% may help mitigate this risk in clinical practice.

Hyperpolarized MRI in Oncology—A Review of Clinical Studies and Evaluation of Preclinical Liver Studies

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Hyperpolarized MRI is a promising clinical imaging modality in oncology, offering at least nine imaging contrasts obtainable with hyperpolarized [1‐13C]pyruvate as the injected agent, depending on the tissue and condition under investigation. Preclinical studies suggest that hyperpolarized MRI is warranted for detecting hepatocellular carcinoma within ...

Retrospective Analysis of Survival and Adverse Effects Associated With Stereotactic Body Radiation Therapy in 12 Dogs With Hepatocellular Carcinoma

Veterinary and Comparative Oncology, Volume 24, Issue 3, Page 485-498, September 2026.
ABSTRACT This retrospective analysis evaluated 12 dogs with hepatocellular carcinoma (HCC) who received stereotactic body radiation therapy (SBRT). Dogs received between 6 and 25 Grey (Gy) per fraction for 1–5 fractions for a total dose of 13–30 Gy. Eleven patients (92%) experienced acute adverse effects (AE), with the majority being VRTOG grade 2–3 ...

Commissioning and clinical positioning assessment of a novel surface‐guided radiation therapy (SGRT) system at a C‐Arm linear accelerator

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Surface‐guided radiation therapy (SGRT) has been increasingly adopted in modern radiotherapy, enabling radiation‐dose‐free, marker‐free patient positioning with high accuracy. A novel SGRT system, LUNA 3D (LAP, Lüneburg, Germany), featuring a browser‐based interface, GPU‐accelerated surface reconstruction, high frame rates, large ...
