【摘要】 热疗作为肿瘤治疗的一种手段已得到很大发展,影响其疗效的关键问题是组织内温度的测量与控制。本系统采用热电耦传感器对温度进行实时采集,利用特解边界元法求解热传导方程得到温度分布,根据数值模拟温度场分布与实际采集的温度值进行对比分析,通过调节交变磁场的频率,从而达到对组织温度的控制。更多还原

【Abstract】 As a technique of oncotherapy,hyperthermia has come a long way.The main thing affecting curative effect is how to measure and control temperature of tissue.In this paper,it introduces a system for temperature monitored control and analysis,which using thermocouple for temperature real-time acquisition.At the meantime particular solution BEM is used to solve Pennes equation for getting temperature distribution.Compared with the temperature of acquisition and simulation,that should control the tissue temperature by adjusting frequency of AC magnet field.更多还原
