Debate THERE ARE MANY EXISTING IGRT OPTIONS FOR HIGHLY ACCURATE DOSE DELIVERY. IS THERE A NEED FOR LARGE-SCALE IN-ROOM MR-GUIDANCE? 14:30 - 15:45 | ROOM 500 There is no doubt that the ideal situation for radiotherapy would be a treatment under more or less static conditions in an ideal dosimetric situation with permanent on-line image based control of the position of tumor, organs-at-risk (OAR) and patient surface. This debate will first outline how close we have already come to this objective with available advanced image guidance strategies and then explore, if/how/where in-room MR-guidance may go beyond current strategies and what requirements must be fulfilled on the way.

Symposium ADDITIONAL TOOLS FOR CONTOURING 14:30 - 15:45 | ROOM 3

As we find ourselves in the era of advanced imaging and adaptive radiotherapy, novel tools that aim to streamline and improve the accuracy of delineation has become the focus of many recent research efforts. In the pre treatment stage, functional imaging such as PET continues to play a role in target volume delineation as we investigate new tracers beyond FDG and explore the role of the biological target volume. At the treatment stage automated tools for deformable registration, recontouring and class solutions will be central to the success of adaptive radiotherapy in a busy clinical environment. This dynamic session will discuss these technologies as we move closer towards personalised radio- therapy.
