Programme

Overview: Adaptive radiotherapy (ART) has become more prevalent as planning and treatment systems advance, allowing for more efficient delivery of care across a wide variety of tumour sites. In order to further improve the quality and efficiency of ART, this symposium aims to provide insight from leading RTT and Physics experts working across different adaptive systems. Topics covered will range from process improvement initiatives, training and credentialing frameworks, the integration of AI and how proton therapy is using adaptive workflows. This symposium will be of great interest to current and future users of adaptive systems.

Overview: Proffered Papers are presented in one of the sessions scheduled in the main session halls. Each author will present orally for 7 minutes, followed by 3 minutes for discussion. Sessions will be recorded and available on-demand.

Overview: Online adaptive radiotherapy (OART) presents an opportunity to account for changes in the patient's anatomy and physiology over the course of treatment, potentially allowing us to target disease more accurately. However, OART also requires a re-evaluation of many aspects of the treatment process, in particular for verification and quality assurance of the online adaptive workflow. In this session, three expert physicists present an overview of the online adaptive workflow and the challenges for QA arising from the transition to OART, the potential solutions to these challenges, and the new risks and the necessary changes associated with plan-specific QA.

Overview: Mini-Orals are presented at one of the sessions scheduled in the two mini-oral theatres. Each author will present a 4-slide PowerPoint orally for 4 minutes, followed by 3 minutes for discussion. Sessions will be recorded and made available via the online platform and mobile app.

Overview: This teaching lecture will focus on motion management strategies specifically when treating oligometastatic disease (OMD) in the thoracic and abdominal regions with SBRT. The lecture will be presented from the viewpoints of both the perspectives of the RTT and the medical physics expert (MPE). The MPE will start the lecture by giving a brief overview of the history of OMD. Concepts such as ITV, MidPos, MidVent and continuous target tracking will be discussed in the line of online adaptive delivery. The MPE will also pose a question over the optimal hardware for such treatment delivery- are ‘traditional’ linear accelerators sufficient or are dedicated, high technology units required? The RTT perspective will take the position of motion management when treating multiple volumes in the same plan on the MR-linac and will refer to the sites most commonly treated in this manner-lung, mediastinum, liver, abdominal volumes and abdominal lymph nodes. The presentation will follow the pathway from pre-treatment to on-treatment, leading to on-treatment decision making by the RTT with specific focus on what planes and which volumes to gate. Finally, some trouble shooting points will be given as well as consideration to questions which are still unanswered in this field.

Overview: Poster Discussions are presented in one of the sessions scheduled at the two poster discussion theatres. Each author will present a digital poster orally for 2 minutes, followed by 2 minutes for discussion. Sessions will be recorded and made available via the online platfrom and mobile app.
