Study on the Microwave Ablation Effect of Inflated Porcine Lung

(1) Background: Microwave ablation (MWA) has an efficient killing effect on primary and metastatic lung cancer. However, the treatment will be affected by air in lung, which makes it very difficult to accurately predict control area; (2) Methods: In this paper, vitro experiments combined with simulations are used study microwave area of inflated porcine lung. The experiment is divided into group deflated group, different power (40 W, 50 60 W) time (100 s, 200 300 s) for experiment, each combination repeated five times. A total 90 were performed. simulation uses COMSOL Multiphysics software simulate lung; (3) Results Conclusions: When 40 average long diameter 20.8–30.9%, 7.6–22.6%, 10.4–19.8% larger than those respectively; short 24.5–41.4%, 31.6–45.7%, 27.3–42.9% that group. results show smaller mainly due diameter.
