Session

Overview: Although particle therapy (PT) is usually considered as the minority in the RT society, the research activities in PT are always sparkling and dynamic. With the joint efforts among the key PT centres in EU and worldwide, the important achievements from RAPTOR consortium will be updated foremost. First, the challenges and solutions for online adaptive PT will be discussed from all aspects of the entire workflow. Then, towards intra-fractional motion, the practical solution and outstanding technical gaps will be presented with a particular rising focus on the longitudinal motion effects. Next, the potential of AI for solving these long-standing PT problems will be elucidated, and attendant challenges on model validation and clinical implementation will be emphasised. Finally, an overview of proton FLASH will be given from aspects of technical realisation, dosimetry, radiobiology and treatment planning.
