This paper designs a multi-stage puncture path planning algorithm of ablation needles for percutaneous radiofrequency ablation of liver tumors, in order to guide or assist clinicians automatically plan the puncture path of ablation needle, and improve the safety and effectiveness of percutaneous radiofrequency ablation for liver cancer. Firstly, the initial feasible puncture paths satisfying the hard constraints are obtained by quantifying different clinical multi-constraint conditions. Then, according to the soft constraints, the risk index of puncture path is designed to realize the first-stage path planning. Read More
