3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, Volume 36, Issue 2, March 2026.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

The American college of radiology diagnostic fluoroscopy dose index registry pilot: Dosimetric performance and benchmarking challenges

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background The ACR Diagnostic Fluoroscopy Dose Index Registry (DIR‐Fluoro) is expanding to include diagnostic fluoroscopy. Variations in dose reference points and overhead radiography events may introduce unique challenges for benchmarking. Purpose To survey the technological status and dosimetric performance of fluoroscopes participating in ...

A feasibility study of functional preservation in craniospinal irradiation with photon for pediatric medulloblastoma

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Craniospinal irradiation (CSI) is essential for treating pediatric medulloblastoma (MB) but causes significant long‐term toxicities. Existing dose‐reduction or partial‐sparing strategies improve neurocognitive outcomes but may compromise survival or fail to address other late effects.

Approaches to needle navigation in interstitial brachytherapy using infrared tracking and radiography

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Intraoperative cone‐beam computed tomography (CBCT) provides a valuable option for accurate three‐dimensional applicator positioning in gynecologic brachytherapy, but is associated with radiation exposure and increased intervention time especially in case of repeated CBCT imaging being required for creating a sufficient implant ...
