间质热疗法组织中温度分布与光纤加入端的关系(英文)

The Relationship of Laser Applicator and Temperature Distribution in Tissue in Laser-induced Interstitial Thermotherapy

主要利用了有限元方法,模拟研究了在激光间质热疗法中,被加热区域组织中温度的分布情况。组织的温度对组织中细胞有着极其重要的影响,对温度的控制是间质热疗法成败的关键因素。到目前为止,在激光间质热疗法中,还没有一种很精确方法能够实时测量激光辐射后组织中温度分布。为了能为临床处理提供一些有用参考,利用Ansys对不同的光纤加入端所形成的温度场进行了模拟,不失为一种好的方法。

In Laser-induced interstitial thermotherapy （ LITT）, the temperature is an important parameter. There is not yet a good method to measure the temperature in tissue after laser irradiation accurately. In order to supply useful reference for surgery therapy, in this article, the relationship of tissue temperature distribution and different laser applicator is researched by using Ansys software to simulate
