Image quality robustness of HyperSight‐enabled versus conventional iterative cone‐beam CT across patient size and imaging geometry

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Recent advances in cone‐beam computed tomography (CBCT) have led to the development of next‐generation CBCT systems with enhanced image quality and quantitative imaging capabilities. These advances are particularly relevant in the context adaptive radiation therapy, where improved soft tissue visualization and Hounsfield unit (HU ...

Automated verification of source dwell position in lunar ovoid applicators

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Accurate reconstruction of the source dwell positions in high‐dose‐rate (HDR) brachytherapy is essential for treatment quality. The Venezia™ gynaecological applicator, with its lunar‐shaped ovoids, poses challenges because conventional dummy markers do not match the actual source path, introducing systematic uncertainties.

Operando Visualization of Cathode Water Management in Proton Exchange Membrane Water Electrolyzers Using Synchrotron X‐Ray Radiography

open access: yesAdvanced Science, Volume 13, Issue 62, 9 November 2026.
The cathode of proton exchange membrane water electrolyzers remains a poorly understood region despite its importance for hydrogen purity and operational safety. Operando synchrotron X‐ray radiography directly visualizes liquid water behavior and uncovers a transition from continuous to pulsating transport, providing new insight into multiphase ...

High‐Temperature Organic Scintillation and X‐Ray Imaging Enabled by a Brominated Pyrazine Phosphor

open access: yesAggregate, Volume 7, Issue 11, November 2026.
A brominated pyrazine phosphor provides a thermally stable organic scintillation system with efficient red phosphorescence and X‐ray conversion capability. Strong intermolecular interactions stabilize the emissive lattice, allowing sustained radioluminescence at elevated temperatures.

Fluids under High Pressure Insighted by Operando Neutron Imaging and Molecular Dynamics Simulations

open access: yesAdvanced Physics Research, Volume 5, Issue 11, November 2026.
There is limited research on how fluids behave under the extreme conditions found in fuel gas systems (high pressure) and catalytic reactors (high temperature and pressure). Neutron Imaging provides experimental data on interfacial tension, and Henry's law volatility constant, apparent molar volume, and diffusion coefficient for systems from toluene ...
