Feasibility of tumour-focused adaptive radiotherapy for bladder cancer on the MR-linac. [PDF]

, 2022
Bladder tumour-focused magnetic resonance image-guided adaptive radiotherapy using a 1.5 Tesla MR-linac is feasible. A full online workflow adapting to anatomy at each fraction is achievable in approximately 30 min. Intra-fraction bladder filling did not

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 ...

Application of Continuous Positive Airway Pressure for Thoracic Respiratory Motion Management: An Assessment in a Magnetic Resonance Imaging–Guided Radiation Therapy Environment

Advances in Radiation Oncology, 2022
Purpose: Patient tolerability of magnetic resonance (MR)–guided radiation treatment delivery is limited by the need for repeated deep inspiratory breath holds (DIBHs).

A randomized phase II trial of MR-guided prostate stereotactic body radiotherapy administered in 5 or 2 fractions for localized prostate cancer (FORT)

BMC Cancer, 2023
Background Ultra-hypofractionated regimens for definitive prostate cancer (PCa) radiotherapy are increasingly utilized due in part to promising safety and efficacy data complemented by greater patient convenience from a treatment course requiring fewer ...

Viewpoint: Optimising Cancer Treatment to Reduce Its Environmental Impact

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT It is widely accepted that treatment and care for patients with cancer must and should happen, as it is what everyone would want for themselves and their loved ones. Everyone wants the best possible care, but climate change and the extreme weather that it causes are increasingly affecting everyone including patients in negative ways.

COMP Report: Patient‐specific quality assurance practices in Canadian radiotherapy—results from a national survey

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Patient‐specific quality assurance (PSQA) is an essential component of modern radiotherapy, ensuring safe and accurate delivery of increasingly complex treatments. Given its resource‐intensive nature and the availability of evolving approaches, examining how PSQA is implemented and optimized across Canada is important to inform best practices.

A preclinical setup for spatially fractionated radiation therapy with electrons

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Spatially fractionated radiation therapy (SFRT) has therapeutic potential as a priming therapy which boosts tumor control. However, the optimal delivery and spatial fractionation parameters have not been deciphered and the mechanisms at play are not yet fully understood.
