Abstract:
OBJECTIVE: To assess the effects of navigation and robot technology on percutaneous ultrasound-guided liver tumor ablation. METHODS:The liver model tumors were placed inside excised calf livers, and the needle was guided into the tumor using either conventional ultrasound-guided method or two new methods-3D navigation and a method based on a robotic assistant. Totally 40 experiments were performed, and the distance (all methods) from the tip of the needle to the planning point in the tumors was measured.RESULTS: Based on the measurements, the robotic assistant performed better than both the 3D navigation and the conventional ultrasound-guided method. While, the 3D navigation performed better than the conventional ultrasound-guided method.CONCLUSTON: This study demonstrates navigation combined with robot technique is feasible to improve the precision of deploying ablation needles, future studies are warranted to optimize the system to meet requirements in clinical practice.
