Simulation and Forecast of Temperature Distribution During Temperature-controlled Radio Frequency Ablation

To explore the temperature distribution surrounding the ablation,which can be helpful to plan individual treatment for patient,a research was conducted during temperature-controlled radio frequency ablation.First,a finite element model with thermostatic excitation was established by using ANSYS to simulate the temperature field.Then,experiments were carried out to validate and improve the model in ex vitro porcine liver and phantom.The results show that the established model is feasible and can be used to predict the temperature field.
