Metaverse and XR (extended reality) are rapidly gaining traction in the medical field, being used to assist surgeries. Leveraging high-speed communication network and advanced XR devices, medical images and surgical procedures are displayed in a three-dimensional space within the metaverse and are shared among physicians. Furthermore, there are initiatives in which novice doctors can relive the techniques of experienced doctors over time, with hopes that it will improve the overall quality and operational efficiency of the medical profession.
