在本文中，能够提供聚焦微波辐射测量和脑深部热疗的混合系统进行了实验测试。该系统的主要模块是一个椭圆形的导电壁腔，作为波束形成器，将电磁能量聚焦在感兴趣的介质上。在过去的几年里，对该系统的微波辐射测量部分进行了广泛的理论和实验研究，取得了可喜的成果。在这项工作中，进一步调查有关的混合系统的聚焦性能的改善进行。具体地说，微波辐射测量和热疗实验进行使用水phantomy周围的电介质层作为匹配材料，以提高检测/穿透深度和空间分辨率。结果表明，介电材料减少了空气-体模界面上的反射电磁能量，从而提高了温度分辨率，并在分别应用微波辐射测量和热疗时提高了能量的检测或穿透。
In this paper a hybrid system able to provide focused microwave radiometry and deep brain hyperthermia is experimentally tested. The system's main module is an ellipsoidal conductive wall cavity which acts as a beam former, focusing the electromagnetic energy on the medium of interest. The system's microwave radiometry component has extensively been studied theoretically and experimentally in the past few years with promising results. In this work, further investigation concerning the improvement of the hybrid system's focusing properties is conducted. Specifically, microwave radiometry and hyperthermia experiments are performed using water phantoms surrounded by dielectric layers used as matching material to enhance detection/penetration depth and spatial resolution. The results showed that the dielectric material reduces the reflected electromagnetic energy on the air–phantom interface, resulting in improved temperature resolution and higher detection or penetration of the energy when microwave radiometry and hyperthermia are applied respectively.
