AR-Guided Liver Surgery with Real Time Tool Tracking Approach

Augmented Reality (AR) enhances liver surgery by providing real-time visualization for precise tumor localization and improved spatial awareness. This investigation integrates preoperative CT and ultrasound data for three-dimensional liver reconstruction utilizing 3D Slicer software. A 3D-printed liver model served as a physical target in Unity for real-time AR visualization. ArUco markers facilitated accurate image tracking and ultrasound guidance. The system aligns virtual and physical models, demonstrating the feasibility of AR-guided liver surgery for real-time navigation and enhanced surgical outcomes.
