How bone mis‐segmentation affects MRI‐based sCT dosimetry in head and neck radiotherapy: A CT‐referenced study

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Magnetic resonance imaging (MRI) is commonly used for head‐and‐neck (H&N) delineation in radiotherapy (RT) owing to the lack of contrast in computed tomography (CT) images. MRI‐based dosimetry is not yet fully developed for the H&N area due to the inter‐patient variability and the difficulty of accurately quantifying cortical bone ...

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 ...

Task‐based image quality and dosimetric validation of HyperSight CBCT for adaptive radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is increasingly used in adaptive radiotherapy (ART), yet the dosimetric accuracy and image quality of advanced CBCT imaging platforms—such as Halcyon HyperSight 4.0 (HH), which combines an upgraded detector panel with advanced iterative reconstruction, scatter‐correction, and metal‐artifact ...

A centralized hybrid model for regulatory inspection readiness in a multi‐site radiation oncology system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background State regulatory inspections of radiation‐producing treatment equipment combine a review of quality assurance and regulatory records with direct verification of facility and safety systems. When these activities are performed entirely on‐site across multiple facilities, real‐time document retrieval can prolong visits and divert ...

Routine physics work efficacy and efficiency improvement through a shared‐duty physicist‐of‐the‐day model in a multi‐hospital radiation oncology network

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Large multi‐hospital radiation oncology networks often rely on site‐exclusive physicist coverage models that can lead to imbalanced workload distribution, inconsistent task execution, communication fragmentation, and vulnerability to delayed or missed quality checks.
