An automated method to establish patient specific asymmetric intrafraction motion monitoring tolerances for prostate radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose Intrafraction motion management is recognized as a critical component of radiotherapy. While clinical trials often recommend its use, they rarely define motion management tolerances. Consequently, institutions set tolerance levels independently, often without considering patient specific anatomy, dose distributions or direction of ...

OVH‐guided planning for superior heart and lung sparing in breast cancer radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background and purpose Manual planning in breast cancer radiotherapy is often time‐consuming and operator‐dependent, leading to inconsistencies in plan quality. This study validated an automated workflow using overlap volume histograms (OVH) to predict patient‐specific dose–volume histogram (DVH) constraints, aiming to enhance cardiopulmonary ...

Comparative analysis of inductively coupled plasma mass spectrometry and alpha spectrometry methods to measure plutonium activity in biosubstrates

Радиационная гигиена
Currently, the most common methods to measure the activity of transuranium elements in biological samples are alpha radiometry and alpha spectrometry. Of these, alpha spectrometry is the most sensitive and selective method.

Impact of CT calibration curves on radiotherapy planning using diagnostic CT scans and a planning CT supporting DirectDensity reconstruction

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose DirectDensity enables tube voltage‐independent, density‐calibrated computed tomography (CT) images for treatment planning and is therefore increasingly used in radiotherapy facilities. In accelerated emergency workflows, diagnostic CT (dCT) data are often acquired without DirectDensity.

Accumulated dose on daily iCBCT for rectal cancer: Effects of inter‐fraction bowel cavity motion volume

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background To assess how inter‐fraction bowel cavity (BC) motion volume influences accumulated dose in rectal cancer radiotherapy and to translate these effects into a clinically interpretable risk construct for acute bowel toxicity. Methods This retrospective cohort included 28 consecutive rectal cancer patients treated with 50 Gy in 25 ...

A controlled trial comparing dosimetry and radiation pneumonitis between tomotherapy and IMRT in patients with lung or esophageal cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Backgroud The expanding clinical use of helical tomotherapy (HT) has raised concerns regarding its potential to increase low‐dose lung exposure and the risk of radiation pneumonitis (RP) in thoracic radiotherapy. While a few retrospective studies have compared dosimetric parameters and RP rates between HT and fixed‐field intensity‐modulated ...
