In developing a microwave tomography system, we started by examining the fundamental signal measurement challenges-i.e., how to interrogate the target while suppressing unwanted multi-path signals. Beginning with a lossy coupling bath to suppress unwanted surface waves, we have developed a robust and reliable system that is both simple and low profile. However, beyond the basic measurement configuration, the lossy coupling medium concept has also informed our choice of array antenna and imaging algorithms. The synergism of these concepts has produced a novel concept which is embodied in a system that has been successfully translated to the clinic.
在开发微波断层扫描系统时，我们首先研究了基本的信号测量挑战，即如何在抑制不需要的多径信号的同时对目标进行探测。从使用有损耦合浴来抑制不需要的表面波开始，我们开发了一个既简单又外形低矮的强大且可靠的系统。然而，除了基本的测量配置外，有损耦合介质的概念还为我们选择阵列天线和成像算法提供了思路。这些概念的协同作用产生了一个新颖的概念，该概念体现在一个已成功转化应用于临床的系统中。
