Efficient laparoscopic ablation of liver tumors relies on accurate positioning of ablation probes, requiring precision in tumor visualization and instrument guidance. We propose a navigation technique that combines intraoperative 2D navigated ultrasound for planning and navigated probe placement with immediate 3D ultrasound based validation of the placement accuracy. In this study, we evaluate accuracy and efficiency of this technique for laparoscopic ablation of liver tumors compared to conventional ultrasound guided probe placement. The results show that ablation probe placements could be performed more efficient and accurate using the navigated approach.
