Latent density discrepancies in commercial lung‐equivalent inserts and their clinical dosimetric impact

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Accurate heterogeneity correction in high‐precision radiotherapy relies on precise computed tomography (CT) number‐to‐density conversion via the Hounsfield unit look‐up table (HLUT). While physical properties of tissue‐equivalent materials are generally assumed consistent with manufacturer specifications, an independent audit ...

Measurements of Radio‐Frequency Electromagnetic Field Levels in EXPO2025 Osaka, Kansai, Japan

Bioelectromagnetics, Volume 47, Issue 5, July 2026.
ABSTRACT In this study, we investigated radio‑frequency electromagnetic field (RF‑EMF) levels at the Expo 2025 Osaka, Kansai, Japan, a large‑scale international event that attracted approximately 26 million visitors during the event period. Spot and portable measurements were conducted for broadcast, 4G, 5G, and ISM bands in both indoor and outdoor ...

Structure delineation in the presence of metal – A comparative phantom study using single and dual-energy computed tomography with and without metal artefact reduction

Physics and Imaging in Radiation Oncology, 2019
Background and purpose: Metal artefacts in computed tomography (CT) images impairs structure delineation. These artefacts can potentially be reduced with dual-energy CT (DECT) with or without using metal artefact reduction (MAR).
