Laparoscopic ablation of liver tumors using ultrasound (US) guidance is a challenging task as it depends on the ability to mentally reconstruct the 3D spatial relationships between the tumor and the ablation needle from 2D ultrasound images. In this work we present a simple 2D ultrasound based image-guidance system for laparoscopic liver tumor ablation. The proposed system provides technology for navigation towards a target which is defined directly in the ultrasound images. To evaluate feasibility of the system, first experiments on a plastic torso including an agar ultrasound phantom were conducted. The results of first experiments by an experienced surgeon using three different guiding modalities show, that by using this system the ablation needle can be placed inside a tumor of 1 cm to 2 cm diameter with a success rate of 100% with two of the three used modalities.
