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.

Multi‐angle fluoroscopic lung perfusion imaging using x‐ray pulsatility index: A pilot study in healthy subjects

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background X‐ray pulsatility index (XPI) quantifies cardiac‐synchronous attenuation changes as a surrogate for regional lung perfusion, but current implementations are limited by projectional overlap and the lack of reference values in healthy individuals. Purpose To characterize regional XPI patterns and establish preliminary reference values

Breast dosimetry using high-resolution voxel phantoms

, 2005
A computer model of X-ray mammography has been developed, which uses quasi-realistic high-resolution voxel phantoms to simulate the breast. The phantoms have 400 μm voxels and simulate the three-dimensional distributions of adipose and fibroglandular ...

A correction to the bandwidth difference method for assessment of magnetic resonance static field homogeneity

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Published guidance offers four methods of static field inhomogeneity (ΔB0)$( {\Delta {{B}_0}} )$ measurement, including a bandwidth difference method. However, an error exists in the implementation of this method, which we demonstrate analytically and experimentally.

Normal tissue complication probability models of late cardiopulmonary toxicity following deep inspiration breath hold for breast cancer adjuvant radiotherapy

Precision Radiation Oncology, Volume 10, Issue 3, Page 307-318, September 2026.
Deep inspiration breath hold (DIBH) markedly cuts heart and left lung radiation doses during left‐sided breast cancer radiotherapy. The normal tissue complication probability (NTCP) model further confirms lower predicted cardiopulmonary toxicities versus free breathing (FB), potentially improving patients’ quality of life.

Feasibility planning study of lattice radiotherapy for palliation in bulky tumors

Precision Radiation Oncology
Purpose Lattice radiotherapy can potentially deliver high doses to the tumor core, while conventional doses to the periphery resulting in improved response rates in large tumors (> 5 cm).

Precise delineation of radiation targets for thoracic tumors in the immunotherapy era: From immune mechanisms to clinical practice

Precision Radiation Oncology, Volume 10, Issue 3, Page 371-387, September 2026.
RT‐immunotherapy synergy for thoracic tumors relies on precise target delineation to protect immune components. IFI, reduced volumes, and optimized positioning minimize damage, while multimodal imaging, DL, PBT, and FLASH‐RT enhance control. These innovations shift RT to an immune‐centric model, improving lung and esophageal cancer outcomes.

A Comprehensive Dosimetric and Plan Quality Evaluation of Non-coplanar VMAT With Flattening Filter-free Versus Flattened Beams for Hippocampal-Avoidance Whole-Brain Radiotherapy: A Multi-Platform Study on Elekta Infinity and UIH uRT-Linac Systems

Technology in Cancer Research & Treatment
Introduction Hippocampal-avoidance whole-brain radiotherapy (HA-WBRT) effectively reduces neurocognitive decline in patients with brain metastases, but evidence from direct multi-platform comparisons remains limited.

Radiation‐Induced Cutaneous Tissue Reactions in Neurointerventional Procedures: A Systematic Review of Reported Effects and Associated Dose Levels

Journal of Medical Imaging and Radiation Oncology, Volume 70, Issue 6, Page 561-572, September 2026.
ABSTRACT Neurointerventional procedures can deliver high localised skin doses and may cause radiation‐induced cutaneous tissue reactions, yet the doses at which these occur have not been synthesised specifically for this setting. We systematically reviewed reported cutaneous reactions and associated radiation doses after fluoroscopy‐ or digital ...

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 ...
