The specific goal of this proposal is to accelerate the clinical translation of SABR, MR-Linac and PBT and to provide an evidence-base for their utility. A key goal of ART-NET is to generate national treatment protocols and to disseminate them across the UK as a means of improving and harmonising practice. In addition, the involvement of medical physicists, research radiographers and clinical research fellows in ART-NET will help to develop a skilled workforce that will be a huge asset for future radiotherapy research in the UK. By achieving these goals, we will improve patient access to state-of-the-art radiotherapy, increase recruitment into clinical trials and ensure sustainability (and expansion) of the research network.
