Towards adaptive radiotherapy: Comparing HyperSight and standard CBCT reconstructions on a C‐Arm Linac

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is integral to image‐guided radiation therapy and increasingly used for adaptive radiotherapy and CBCT‐based dose calculation. Conventional kV‐CBCT systems on C‐arm TrueBeam linacs with Feldkamp–Davis–Kress (FDK) reconstruction have historically been limited by reduced Hounsfield Unit (HU ...

Computational retrospective dosimetry with fortuitous dosimeters: An inter-laboratory comparison and evaluation of dose conversion coefficients

Nuclear Engineering and Technology
In large-scale radiological accidents, retrospective dose assessment is crucial for individuals without personal dosimeters. This study investigates the applicability of computational dosimetry and dose conversion coefficients (DCCs) using mobile phones ...

Micronucleus assay in rapid retrospective biological dosimetry [PDF]

, 2016
Rapid retrospective biological dosimetry allows absorbed dose evaluation post exposure to ionizing radiation. One of the main tools of biodosimetry is based on the analysis of the effects resulting from the impact of ionizing radiation on the cell ...

Routine physics work efficacy and efficiency improvement through a shared‐duty physicist‐of‐the‐day model in a multi‐hospital radiation oncology network

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Large multi‐hospital radiation oncology networks often rely on site‐exclusive physicist coverage models that can lead to imbalanced workload distribution, inconsistent task execution, communication fragmentation, and vulnerability to delayed or missed quality checks.

Comparison of in‐field secondary cancer risk based on therapeutic proton dose between proton arc therapy and intensity‐modulated proton therapy in lung cancer patients

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Proton arc therapy (PAT) is an emerging delivery modality that delivers proton beams through continuous gantry rotation combined with spot scanning. Compared with intensity‐modulated proton therapy (IMPT), PAT improves target conformity and spares organs at risk. However, the dynamic multi‐angle irradiation pattern may alter the low‐

Commissioning a single photon counting CT simulator for radiotherapy planning: Methods, challenges, and initial results

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Photon counting computed tomography (PCCT) offers distinct advantages over standard energy‐integrated detector (EID) CT by offering energy‐resolved measurements, enhanced spatial resolution, and improved soft‐tissue contrast. While PCCT shows great utility in diagnostic imaging, its application as a radiotherapy simulator has not ...

Evaluating Human Perception Thresholds in Magnetic Stimulation Using Experimental Measurements and Modelling

Bioelectromagnetics, Volume 47, Issue 6, September 2026.
ABSTRACT This preregistered study investigated whether induced electric fields alone could predict human perception thresholds in magnetic stimulation. Using a figure‐of‐eight magnetic coil placed on the forearm, perception thresholds were collected from 24 healthy participants using the method of adjustment in 12 stimulation conditions. Subject‐fitted,

Problems related to retrospective dosimetry of exposure delivered at low dose rates

, 1998
Biological dosimetry has pl oven its utility in cases of single acute whole-body exposure, but encounters difficulties when only parts of the body have been exposed, and when the irradiation has been delivered over longer periods of time due to ...
