Online adaptive radiotherapy in stereotactic body radiotherapy for pancreatic cancer patients

Scientific Reports
Stereotactic radiation therapy (SBRT) has emerged as a promising treatment modality for locally advanced pancreatic cancer. The aim of this study is to assess the dosimetric efficacy of online adaptive radiotherapy (ART) in comparison to image-guided ...

Evaluation of the environ SRS immobilization mask system for HyperArc: Dosimetric attenuation, dose calculation accuracy, and clinical setup reproducibility

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Frameless thermoplastic masks are standard for intracranial stereotactic radiosurgery (SRS), with the Encompass (CQ Medical) widely used on the Varian HyperArc platform. A candidate mask must minimize beam attenuation, permit accurate dose calculation, and enable reproducible setup, yet these are rarely assessed together ...

Beam geometry optimization and convergence mode evaluation for knowledge‐based planning of hippocampal avoidance whole‐brain radiotherapy: A cross‐platform study with quantitative scorecard assessment

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Hippocampal avoidance whole‐brain radiotherapy (HA‐WBRT) is used to treat brain metastases while preserving cognitive function by sparing the hippocampi. Volumetric modulated arc therapy (VMAT) is commonly used due to its ability to generate conformal dose distributions.

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.

Towards adaptive radiotherapy: Comparing HyperSight and standard CBCT reconstructions on a C‐Arm Linac

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is integral to image‐guided radiation therapy and increasingly used for adaptive radiotherapy and CBCT‐based dose calculation. Conventional kV‐CBCT systems on C‐arm TrueBeam linacs with Feldkamp–Davis–Kress (FDK) reconstruction have historically been limited by reduced Hounsfield Unit (HU ...

A group‐based hands‐on seminar for teaching failure mode and effects analysis in CyberKnife stereotactic radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Risk analysis is becoming increasingly important in advanced radiotherapy, as treatment workflows grow more complex and require multidisciplinary expertise. Although failure mode and effects analysis (FMEA) has been recommended for risk‐based quality management, opportunities for users to practically learn and apply FMEA within ...

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.

Log file‐based treatment efficiency analysis of TrueBeam and Halcyon delivery systems

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background TrueBeam (TB) and Halcyon (HC) are state‐of‐the‐art linear accelerators (linacs) widely utilized for external beam radiotherapy. As clinical demand increases, expanding treatment capacity through new machine installations or extended operating hours remains costly and resource intensive.
