Markerless Augmented Reality Registration for Surgical Guidance: A Multi-Anatomy Clinical Accuracy Study
Researchers have developed a markerless augmented reality (AR) system for surgical guidance that uses only depth data from a head-mounted display. The system aligns depth scans with CT-derived skin meshes, achieving median errors of around 3-4 mm in clinical trials across feet, ears, and lower legs. This approach, which includes human-guided initialization and a global-to-local registration process, shows promise for improving the accuracy and clinical readiness of AR in surgery, particularly for anatomies with low curvature.
