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
