Session

Overview: In this session we will start with Martin Fast, who will be discussion various real-time motion mitigation techniques to deal with periodic cardiorespiratory motion, including tracking, trailing, gating, and intra-fractional re-planning. Subsequently, Pierluigi Bonomo will discuss how do deal with unpredictable non-periodic target motion and deformation. He will discuss intrafraction GTV changes in rectal and prostate cancer, and how MR-guidance can be used to deal with these. In the third lecture Simon Skouboe will provide his insights into how real-time dose accumulation can be used to detect potential under- or over-dosing, and how act on these. In the last lecture, Stephen Bowen will give an overview of imaging biomarkers that can be used to predict or measure biological response to treatment, and how they can be used to adapt radiation therapy.
