Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

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 ...
