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
