In burn surgery, full-thickness burns must be excised, while partial-thickness burns can heal with less aggressive intervention. It is often difficult to identify the difference between these two types of burn by eye, which can result in surgeons excising more tissue than necessary. This can increase the risk of complications due to skin grafts. Several imaging technologies have emerged recently to identify the difference between the two types of burns. However, these imaging techniques produce a planar image, which can be difficult for surgeons to trace from. Using mixed reality, we can register the planar image on the anatomy and add depth, allowing surgeons to trace the planar image with higher accuracy.
