Conclusions
Advanced delivery systems are complex and non-intuitive and are challenging QA Gamma index is useful to monitor e.g. machine consistency and major failures, but it correlates poorly with clinically relevant parameters 3D dose reconstruction and DVH analysis for patient specific QA provides better clinically interpretable results, but careful consideration of the method used for dose reconstruction is required Image QA of on-board imaging devices is not well established in radiotherapy E2E testing of advanced treatments should be mandatory before the first patient treatment QA of treatment planning is often undervalued
