6D Setup Reproducibility and Immobilization Capability of Frameless Stereotactic Mask System

Event: 4th International Conference of the Novalis Circle 2008
Topic: Positioning and Monitoring
Year: 2008

Nadine Linthout from the Universitair Ziekenhuis Brussel discusses 6D setup reproducibility and the immobilization capability of frameless stereotactic mask systems. She begins by outlining how they used to achieve positioning accuracy through the use of earplugs fitted with lead beads that would appear in scans to align the patient. She goes on to discuss current immobilization systems and the advantages of 6D setup correction. She then delves into frame-based positioning and frameless positioning, giving clinical examples including results of patient positioning at her facility.

Thank you. My presentation will partially overlap with the presentation that we had before about the intrafraction movements, but we still found some other values, I hope this will still be interesting. Now as an introduction, I want to mention again that the CTV to PTV margin should reflect the accuracy of the target localization. And in order to achieve this, we have to optimize both the setup and the internal margins. Now, a long time ago, we improved the setup margin, by the introduction of thermoplastic mask for immobilization for the patient. Now, what we did, we saw between...
