Optimizing TrueBeam jaw calibrations to reduce positional errors at customizable gantry and collimator angles

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Clinical medical physicists in a radiotherapy setting are aware of the importance of maintaining linac collimators with high positional accuracy, especially when used to form junctions; however, there is a lack of quality control options available.

Image quality robustness of HyperSight‐enabled versus conventional iterative cone‐beam CT across patient size and imaging geometry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Recent advances in cone‐beam computed tomography (CBCT) have led to the development of next‐generation CBCT systems with enhanced image quality and quantitative imaging capabilities. These advances are particularly relevant in the context adaptive radiation therapy, where improved soft tissue visualization and Hounsfield unit (HU ...

Reporting treatment planning, delivery, and dose evaluation for 3‐dimensional MLC‐based SFRT: A single institutional clinical experience

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Purpose/Objective We report our institutional clinical experience of treatment planning, dose evaluation, and delivery via the same‐day 3D MLC‐based crossfire method for spatially fractionated radiotherapy (SFRT) in conjunction with combination therapy. Additionally, we aimed to model our clinical outcome data to provide clinical insights into

Daily Multi‐Leaf Collimator positional error prediction using machine learning: A Dynalog‐based approach for patient specific quality assurance

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Accurate positioning of multi‐leaf collimators (MLCs) is critical for ensuring the dosimetric precision of intensity‐modulated radiation therapy (IMRT). Nonetheless, daily MLC positional variations can degrade treatment accuracy, emphasizing the need for robust methodologies to detect and predict these deviations. Purpose This study

Development of a low‐cost 3D‐printed phantom for end‐to‐end testing of model‐based dose calculation algorithms (MBDCAs) in high‐dose‐rate (HDR) brachytherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Model‐Based Dose Calculation Algorithms (MBDCAs), such as AcurosBV, have improved dosimetric accuracy in high‐dose‐rate (HDR) brachytherapy by accounting for medium heterogeneities and variations in scatter conditions. However, their safe and effective clinical implementation requires thorough commissioning, of which end‐to‐end (E2E)
