consistent segmentation of the regions of interest, as well as standardization of image acquisition- and reconstruction protocols. Furthermore, the sparsity of the data is often a major challenge. While deep learning has been successfully used for multiple classification and prediction tasks, it hasn’t been widely explored for longitudinal medical image analysis. Nevertheless, deep learning is able to automatically learn complex and abstract representations from large amounts of data and identify subtle changes that are difficult for the human eye to detect. Besides modelling temporal relationships, deep learning could be used to fuse information extracted from different image modalities to make more accurate predictions. Ideally, longitudinal information from cross-modality images would be captured and integrated with information from complementary biomarkers. Some examples on longitudinal outcome prediction using deep learning can be found in literature. This ranges from the use of longitudinal magnetic resonance imaging to predict response after neoadjuvant chemoradiotherapy for rectal cancer patients, to the development of a deep learning-based deformable image registration algorithm proposed for longitudinal imaging studies and adaptive radiotherapy.

Symposium: Use of virtual reality in radiotherapy

SP-1050 VR in patient education TBC Abstract not available

SP-1051 VR in paediatric radiotherapy N. Anderson 1 1 Olivia Newton John Cancer Wellness & Research Centre, Austin Health, Radiation Oncology, Melbourne, Australia Abstract Text Procedural stress and anxiety induced by radiation therapy provides many challenges for the radiation oncology clinical team. These stressors are further exacerbated in the paediatric setting, where comprehension is routinely poorer, impacting compliance to the many steps staggered throughout the radiation therapy treatment journey. In many circumstances, general anaesthesia is introduced to enable safe, precise, efficient treatment planning and delivery for paediatric patients overwhelmed and unable to comply with this requirement. Virtual reality (VR) has been long used as a tool to immerse its users into a virtual environment to create life-like experiences. In recent years, VR has made an exciting transition into healthcare, utilised as both a tool for distraction and education in both the adult and paediatric settings across multiple specialities. The interactive nature of the VR platform has a particular lure to a paediatric audience. Recent evidence has demonstrated the successful application of VR into the paediatric radiation oncology setting, with a focus on improving health literacy of the radiation therapy process, which in turn, aimed to reduce procedural related anxiety. Both provided significant benefits, with improved health literacy in paediatric patients and reduced anxiety in paediatric patients and parents alike. Additionally, further operational benefits were witnessed through improved efficiencies afforded by these health literacy and anxiety-related wins. This presentation will further discuss this research and other emerging evidence in the VR in paediatric radiation therapy domain. Furthermore, new and exciting opportunities for the application of VR in radiation oncology will be discussed, with the audience engaged as to where they feel the future of VR in radiation therapy is headed as the never-ending possibilities of this technology are realised. Abstract Text During the presentation I would like to make the link between the VERTUAL system (virtual learning system radiotherapy) as training support for students or future colleagues RTTs and the use of the system as an education tool to patients. In my department, the system is used for both purposes. In general, little literature is currently available regarding the virtual world of radiotherapy. There are a few projects underway, and my department will also conduct further research on this in the near future. You can use different methodologies to link VR in a process of education. I would like to involve the VERTUAL system in this. We have thought about the process and how/when we can best fit the educational moment into the treatment process. We have provided sessions for the group of pelvic gynaecology patients, but also for all patients who are irradiated in the pelvis/abdomen. This session focuses on the 'virtual', that which the patient experiences as unknown. The irradiation room, the irradiation device. The importance of positioning, use of mobilization devices are also explained. We also zoom in on the treatment, the imaging part and we link to IGRT protocols. We experienced that patients are even better informed about their treatment in this way and that they feel calmer and reassured. SP-1052 VR in gynaenocology radiotherapy L. Van den Berghe 1 , V.D.B.
