Complementary Breath Profiling Using eNose and Gas Chromatography‐Mass Spectrometry for Noninvasive Triage of Indeterminate Pulmonary Nodules

MedComm, Volume 7, Issue 10, October 2026.
Flow diagram illustrating participant inclusion and exclusion for the eNose and GC‐MS analyses. Of the 98 prospectively enrolled participants, 79 were eligible for the eNose analysis after the exclusion of 14 participants because of procedural or eligibility issues, four without breath samples, and one without a valid eNose recording.

Respiration Patterns of Southern Right Whale (Eubalaena australis) Mothers and Calves in Southern Brazil

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Respiration is a key physiological process in cetaceans, closely linked to energy expenditure, behavior, and physiological state. Using drone‐based surveys, we quantified respiration patterns of southern right whale (Eubalaena australis) mother–calf pairs in southern Brazil across two reproductive seasons (2020–2021).

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.

Pulmonary ventilation images from planning CT images using deep learning on locally‐advanced NSCLC patients

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Pulmonary ventilation imaging has become an increasingly important component in thoracic radiotherapy, as it is applied to functional avoidance radiotherapy, where radiation doses are strategically minimized to preserve functional lung regions.

Development of exhaled breath analyzer

This study investigates the elevated levels of acetone found in the exhaled breath of diabetic patients compared to healthy individuals. A gas sensor, constructed from Zinc Oxide nanoparticles, will be employed to quantify the acetone concentration in ...

Evaluation of inter‐fractional anatomical variations due to compression belt placement reproducibility using MR‐guided radiotherapy treatment fraction images

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Abdominal compression (AC) using a belt‐based system is widely employed in radiation therapy to limit respiration‐induced target motion for abdominal and hepatic malignancies. While AC has demonstrated efficacy in reducing intrafraction motion amplitude, the interfractional anatomical consequences of daily compression belt (CB ...
