Abstract:
This paper reports on an effective ablation volume model for microwave ablation of porcine liver. Firstly, in order to obtain the temperature field distribution, a theoretical simulation model of the microwave ablation of porcine liver was developed by solving Pennes bioheat transfer equation using the COMSOL Multiphysics software. Then the effective ablation volume and the effective ablation volume model were obtained using the 1stOpt fitting software by 7D-Soft High Technology Inc. (China). Finally, microwave ablation experiments were carried out using porcine liver to verify the accuracy and effectiveness of the model. The results show that according to the ablation volume model, one can determine the scope of the effective ablation under varying conditions of microwave power and duration. This provides an important basis for the preoperative planning system of microwave ablation.
Zusammenfassung:
Die vorliegende Arbeit berichtet über ein effektives Ablationsvolumen-Modell für die Mikrowellenablation von Schweineleber. Zuerst wurde ein theoretisches Simulationsmodell durch Lösen der Bio-Wärmetransfer-Gleichung von Pennes unter Verwendung der COMSOL Multiphysics Software entwickelt, um die Temperatur-Feldverteilung in Schweineleber zu ermitteln. Danach wurde das effektive Ablationsvolumen durch ein Ablationsvolumen-Modell unter Verwendung der 1stOpt Fitting-Software (7D-Soft High Technology Inc., China) bestimmt. Schließlich wurden Mikrowellenablations-Experimente mit Schweineleber durchgeführt, um die Genauigkeit und Effektivität des Modells zu überprüfen. Die Ergebnisse zeigen, dass unter Zugrundelegung des Ablationsvolumen-Modells der Umfang der effektiven Ablation unter variierenden Bedingungen von Mikrowellenleistung und Applikationsdauer bestimmt werden kann. Dies stellt eine wichtige Grundlage für ein präoperatives Planungssystem der Mikrowellenablation dar.
