A patient (age older than 60 years) had a HCC tumor (2.4 cmx2.1cmx1.9 cm in diameter) located in S6 who underwent 3D visualization preoperative planning (a-c). The lesion (red) was segmented rapidly, which can stereo display in the 3D visualization before microwave ablation. The whole lesion was covered by suitable thermal field sphere generated from two antennas in 3D visualization ablation planning system. The ablation area (green) was segmented rapidly, which can stereo display in the 3D visualization after microwave ablation (d-e). A clear-boundary, regular-form tumor was showed in the CEUS image. According to 3D visualization preoperative planning, two antennas inserted in tumor under US-guided. Postoperative ablation area was showed in CEUS image
