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

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...
