Log file‐based patient‐specific quality assurance for MR‐guided radiation therapy with comprehensive motion management

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Patient‐Specific Quality Assurance (PSQA) for Elekta Unity MR‐Linac treatments delivered under Comprehensive Motion Management (CMM) is challenging because beam gating, unexpected interruptions, and split sub‐segments introduce delivery complexities that are not fully addressed by conventional quality assurance workflows.

Dosimetric impact of aperture‐restricted VMAT on heart dose in breast cancer treated with regional nodal irradiation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Volumetric modulated arc therapy (VMAT) is increasingly used for breast and chest wall (CW) treatment with regional nodal irradiation (RNI) because of its ability to sculpt dose around complex target volumes. However, VMAT can increase low‐dose radiation to surrounding normal tissues and particularly increase cardiac dose.

Fluorescence in situ hybridisation for interphase chromosomal aberration-based biological dosimetry

, 2023
Metaphase spreads stained with Giemsa or painted with chromosome-specific probes by fluorescence in situ hybridisation (FISH) have been in use since long for retrospective dose assessment (biological dosimetry).

A Monte Carlo based dose verification tool for an HDR Ir‐192 brachytherapy source and its evaluation on extremity malignancies

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background TG‐43 formalism dose calculation for brachytherapy with the homogeneous water‐based assumption is widely used, which can lead to dose inaccuracy in treatment planning. Purpose Extremity malignancies are also treated with high‐dose‐rate (HDR) 192Ir interstitial brachytherapy, a treatment site that has not been specifically ...

Reducing the dose delivered to major intracranial blood vessels in brain radiotherapy using spot‐scanning proton arc therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Glioblastoma (GBM) patients have poor clinical prognoses, which may partially be explainable by correlations between radiation‐induced killing of circulating blood cells (CBCs) and worse clinical outcomes. Proton radiotherapy is currently delivered via intensity‐modulated proton therapy (IMPT), for which the target is irradiated ...
