摘　　要：目的 :探讨有限元模型在射频消融设备教学中的应用。方法 :通过COMSOL软件对肝脏射频消融进行有限元建模,在教学中模拟消融温度、损伤范围随时间的变化,加深学生对射频消融设备的理解。结果:有限元模型可以模拟消融温度、损伤范围随时间的变化,学生能够更好地理解射频通过热效应对病灶进行消融的原理。结论:采用有限元模型辅助进行射频消融设备的教学,有利于提高学生的学习兴趣,培养其创新能力。Objective To explore the application of finite element model in teaching radiofrequency ablation device.Methods A simple finite element model of radiofrequency hepatic tumor ablation was built with COMSOL. The tempera ture field and the region of necrotic tissue were simulated with the model for radiofrequency ablation device to deepen understanding of the device. Results The model could simulate the changes of temperature and the students could understand the resistive heating process easily. Conclusion Finite element model can improve the students in learning interest and innovation ability.
