Markerless AR system achieves 3-4mm surgical guidance accuracy

By PulseAugur Editorial · [1 sources] ·

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.

IMPACT This markerless AR system could enhance surgical precision and reduce reliance on physical markers, potentially improving patient outcomes.

    Markerless Augmented Reality Registration for Surgical Guidance: A Multi-Anatomy Clinical Accuracy Study

    arXiv:2511.02086v2 Announce Type: replace Abstract: Purpose: In this paper, we develop and clinically evaluate a depth-only, markerless augmented reality (AR) registration pipeline on a head-mounted display, and assess accuracy across small or low-curvature anatomies in real-life…
