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 ...

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.

Transit dosimetry of stereotactic body radiotherapy treatments with electronic portal dosimetry device in patient with spinal implant

Physical and Engineering Sciences in Medicine, 2022
Abstract Aim In recent years, the use of the Electronic Portal Imaging Device (EPID) as an in vivo dosimeter has become widespread. However, reports of EPID for stereotactic body radiotherapy (SBRT) applications is scarce. There is no data on this topic especially when there are high-density materials in the radiation field.

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...
