A. Martin-Gomez, J. Fotouhi, N. Navab Towards Exploring the Benefits of Augmented Reality for Patient Support During Radiation Oncology Interventions Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization (bib)
	Traditionally, patient education has been limited to verbal exchanges between providers and patients, along with paper handouts that try to summarize relevant information. While such exchanges are a natural first step in educating patients, they are limited for several reasons, including the lack of time that provider teams are afforded, and the inherent challenge of communicating nuanced concepts related to complex medical procedures. A clear example of this is radiation oncology, in which traditional routes of patient education may not satisfy the patient's needs. Although existing work has demonstrated the ability of audio-visual systems to improve patient engagement during medical procedures, the integration of emerging technologies such as Augmented Reality (AR) remains largely untapped. In this work, we propose the development of an innovative proof-of-concept AR system as a first step towards exploring the benefits of using this technology during radiotherapy sessions. Our concept can provide visual feedback of the patient’s respiratory trace using an AR headset. This information is presented in two different forms that can be chosen by the patient: (i) a bi-dimensional graph and (ii) a game-based user interface. In this regard, we explore how interactive environments such as games have the potential to contribute to better user experience and improve engagement. Furthermore, we discuss the different challenges that must be addressed to successfully deploy this technology to radiation treatment sessions.
