Quality assurance of single isocentre multiple target stereotactic radiosurgery: Findings from long‐term off‐axis Winston‐Lutz testing and machine performance checks

Journal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.
Abstract Background Single‐isocenter multiple‐target stereotactic radiosurgery (SIMT SRS) has emerged as an efficient treatment for multiple brain metastases. However, this technique demands exceptional geometric accuracy, particularly off‐axis, to ensure optimal dose delivery while sparing healthy tissue.

Optimization of Replanning Processes for Volumetric Modulated Arc Therapy Plans at Risk of QA Failure Predicted by a Machine Learning Model

Applied Sciences
Patient-specific quality assurance (PSQA) procedures ensure the safe delivery of volumetric modulated arc therapy (VMAT) plans. PSQA requires extensive time and resources and may cause treatment delays if replanning is needed due to failures.
