Australian Society of Medical Imaging and Radiation Therapy Image Registration in Radiation Therapy Position Paper

Journal of Medical Radiation Sciences, Volume 73, Issue 3, Page 345-351, September 2026.
The ASMIRT Image Registration Working Party outlines the critical role of radiation therapists in performing, assessing and documenting rigid and deformable image registration across treatment planning, delivery and adaptive workflows. The position paper emphasises consistent nomenclature, robust QA processes, strong collaboration with diagnostic ...

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

Journal of Medical Radiation Sciences, Volume 73, Issue 3, Page 250-258, September 2026.
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

Inverse‐consistent deformable image registration to propagate biomechanical constraints for online adaptive radiotherapy

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Accurate motion estimation remains a key challenge in adaptive radiotherapy (ART). Voxel‐wise accuracy is required, as registration errors can compromise the treatment quality. Locally constrained image registration is a promising technique to further improve ART treatment, but relies heavily on quick and accurate delineations of ...

Case report: Clinical workflow considerations for treating soft-tissue sarcoma on a 1.5-T MR-Linac

Technical Innovations & Patient Support in Radiation Oncology
We present specific issues that arose when using a 1.5-Tesla MR-Linac to treat a series of 4 soft-tissue sarcoma (STS) patients. These issues arose from the combination of typical STS attributes (long, off-axis target) and MR-Linac design-specific ...

Roadmap for the implementation of particle minibeam therapy

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Particle minibeam therapy (PMBT) has emerged as an advanced modality within spatially fractionated radiation therapy, using the physical properties of protons, ions, and electrons to achieve superior normal tissue sparing whilst preserving spatial dose distribution at depths that are unachievable in conventional kV or MV X‐rays.

Radiotherapy and Immunotherapy In Hepatocellular Carcinoma: Priming the Tumor Immune Microenvironment From Bench To Bedside

Precision Radiation Oncology, Volume 10, Issue 3, Page 417-427, September 2026.
The dual immunomodulatory network of radiotherapy in hepatocellular carcinoma. Radiotherapy initiates its effects by inducing immunogenic cell death and DNA double‐strand breaks. Immune Activation: Cytosolic DNA from damaged cells activates the cGAS‐STING pathway, triggering IRF3/NF‐κB‐mediated type I interferon production. This enhances dendritic cell

Feasibility of celiac axis delineation and treatment on combined magnetic resonance imaging and linear accelerator systems

Physics and Imaging in Radiation Oncology
Trials have been performed on irradiating celiac plexus for pancreatic cancer pain management. Images from a combined magnetic resonance imaging and linear accelerator system (MR-linac) for ten patients were assessed for delineation of celiac ganglia ...
