微波热疗法是治疗癌症的方法之一。微波热疗就是一个例子，它是一种基于加热降低癌细胞存活率的癌症热疗法。特别是我们一直在研究用植入的胆道支架和同轴微波探针结合内窥镜进行腔内加热，这是一种有效的、低侵入性的治疗胆管癌等深部肿瘤的方法。本文通过肌肉等效模体的加热实验和时域有限差分（FDTD）方法的数值模拟来描述胆道支架周围的加热特性。
Microwave thermal therapy is one of the modalities for cancer treatment. One example is microwave hyperthermia which is a thermal therapy for carcinoma based on the decrease of the survival ratio of cancer cells by heating. In particular, we have been studying the intracavitary heating using the implanted biliary stent and a thin coaxial microwave probe combined with endoscope which is an effective and low-invasive treatment for deep-seated carcinoma such as a bile duct carcinoma. This paper describes the heating characteristics around the biliary stent by conducting both the heating experiments using muscle-equivalent phantom and the numerical simulations using the finite-difference time-domain (FDTD) method.
