Conclusions: Intra-cranial
Why adopt non-invasive, frame-less IGRT for stereotactic techniques?
Frame-less fractionated cranial SRT
Improved accuracy
Efficient work-flow
Frame-less single fraction cranial SRS
Patient comfort, no risk of bleeding or infection
More time for multi-modality, complex treatment planning
No difference in accuracy ?
Consistent work-flow with optimization of all steps of radiotherapy
planning and delivery, strict QA and definition of standardized
protocols to achieve maximum accuracy of treatment
