SYMPOSIUM Improving delineation in RT: not only for the doctor 11:00 - 12:15 | Space 1-2

Our current state of the art radiotherapy techniques provided themeans to deliver dose conformal to the target at sub-millimeter precision. However, the target and normal structures as such still contain a significant level of uncertainty, and delineation can therefore be seen as the weakest link in the radiotherapy chain. Apart from generating consensus delineation guidelines and organizing education, advances in imaging can play an important role in reducing interobserver variability. Also, dedicated software tools for delineation including auto-contouring can contribute to better and more consistent delineation practice. This session will provide an introduction to interobserver variability measures and implications, show the value of DECT and MR techniques for delineation, and finally place delineation uncertainty in the bigger picture of uncertainties in radiotherapy. 11:00 > How to handle clinical inter-observer variation in contouring assessment Speaker: M. Gooding (United Kingdom) 11:18 > CT-based delineation: What can we gain from state-of-the-art CT image acquisition and reconstruction techniques Speaker: C. Richter (Germany), F. Negwer, E.C. Troost, P. Wohlfahrt 11:36 > Development of MR techniques focused on improved delineation Speaker: M. Philippens (The Netherlands) 11:54 > The future of margins in the era of new (multi-modality) imaging technology Speaker: J .Stroom (Portugal), S. Vieira, C. Greco Chair: T. Nyholm (Sweden) Co-chair: C. Brouwer (The Netherlands)
