This study introduces a new method for planning percutaneous hepatic microwave ablation surgery. The technique accurately simulates and reconstructs the tumor necrosis zone, aiding surgeons in achieving optimal treatment plans for liver cancer.
Area of Science:
- Medical Imaging
- Surgical Planning
- Computational Modeling
Background:
- Percutaneous hepatic microwave ablation is a common treatment for liver cancer.
- Accurate preoperative planning is crucial for effective ablation and minimizing complications.
- Current planning methods may lack precision in predicting the ablation zone.
Purpose of the Study:
- To develop and evaluate a novel preoperative surgery planning method for percutaneous hepatic microwave ablation.
- To introduce an iterative framework for necrosis field simulation and 3D reconstruction.
- To integrate simulated necrosis zones with patient-specific anatomy for interactive surgical planning.
Main Methods:
- Developed an iterative framework for simulating necrosis field and reconstructing the 3D necrosis zone.
- Utilized GPU-accelerated visualization techniques to superimpose the necrosis model onto patient anatomy.
- Conducted interactive surgery planning sessions with surgeons.
- Validated the method using realistic patient data with hepatic cancer.
Main Results:
- The proposed method demonstrated relative accuracy in preoperative trajectory planning.
- Postoperative CT images were used to measure the actual necrosis zone for comparison.
- The simulation and reconstruction framework effectively predicted the ablation outcome.
Conclusions:
- The novel method provides an accurate approach for preoperative planning of hepatic microwave ablation.
- The technique can serve as a valuable assistant tool in clinical practice for liver cancer treatment.
- Interactive planning enhances the ability to achieve optimal surgical outcomes.
