Evaluation of the accuracy of an enhanced MLC leaf model for Linac‐based stereotactic radiosurgery

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Purpose For LINAC‐based stereotactic radiosurgery (SRS) treatments, the binary MLC models utilizing single dosimetric leaf gap (DLG) parameters in Eclipse versions prior to v18 can result in imperfect agreement between measured and calculated doses, increased commissioning complexity, and user‐dependent variability. This study aims to evaluate

Novel validation of HDR brachytherapy dosimetry for cervical cancer using egs_brachy Monte Carlo simulations: a comparative analysis with Oncentra treatment planning system

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Purpose This study aims to validate HDR brachytherapy dosimetry for cervical cancer patients utilizing the egs_brachy Monte Carlo (MC) simulation. Methods Three cervical cancer patients treated with 192Ir HDR brachytherapy were included. Dose distributions were calculated by the Oncentra Brachy v4 treatment planning system (TPS) based on AAPM ...

Quantitative patient‐specific quality assurance prediction using MLC mean leaf gap and PTV volume

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Rigorous patient‐specific quality assurance (PSQA) is essential to radiation therapy safety. As logfile‐based PSQA gains adoption, quantitative methods to select certain high‐complexity treatment plans for additional measurement‐based PSQA can help to ensure a comprehensive QA program.

Clinical feasibility of atlas‐based auto‐segmentation for organ‐at‐risk contouring in head‐and‐neck radiotherapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Purpose Head‐and‐neck (HN) contouring presents significant challenges due to the complex anatomy of the region and the proximity of organs‐at‐risk (OARs) to the target. Manual contouring is time‐consuming, labor‐intensive, and prone to inter‐ and intra‐observer variability.
