dc.description.abstractObjective: The objective was to investigate the law of three-dimensional thermal field radiation of ceramic slot microwave (CSMW) ablation antenna. Materials and Methods: First, microwave ablation experiments were performed with phantom and temperature data were collected. Second, the specific absorption rate distribution function of microwave (MW) ablation antenna was fit. Third, the MW ablation thermal field morphology was simulated based on the rapid simulation method. In addition, to determine the thermal field simulation accuracy, comparative analysis on the ablation morphology of forty clinical patients with liver cancer receiving percutaneous treatment was conducted. Results: Regarding the ablation morphology, the CSMW ablation antenna had greater long and transverse diameters and ablation volume than the polytetrafluoroethylene slot microwave (PSMW) ablation antenna (P < 0.05). Compared with the actual ablation morphology in clinical practice, the error rate in long and transverse diameters of the simulated morphology of thermal field was up to 5% and the minimum was 1.2%, whereas the maximum volume error rate was up to 9.8%. Conclusion: The CSMW ablation antenna had a greater long diameter, transverse diameter, and volume regarding the ablation morphology than the PSMW ablation antenna, and the thermal field morphology obtained based on the rapid simulation algorithm had a high accuracyen_US
