Microwave imaging of the breast is of interest for monitoring breast health, and approaches to active microwave imaging include tomography and radar-based methods. While the literature contains a growing body of work related to microwave breast imaging, there are only a few prototype systems that have been used to collect data from humans. In this paper, a prototype system for monostatic radar-based imaging that has been used in an initial study measuring reflections from volunteers is discussed. The performance of the system is explored by examining the mechanical positioning of sensor, as well as microwave measurement sensitivity. To gain insight into the measurement of reflected signals, simulations and measurements of a simple phantom are compared and discussed in relation to system sensitivity. Finally, a successful scan of a volunteer is described.
乳腺的微波成像对于监测乳腺健康具有重要意义，主动式微波成像方法包括断层扫描和基于雷达的方法。虽然文献中与微波乳腺成像相关的研究日益增多，但仅有少数原型系统被用于收集人体数据。本文讨论了一种基于单基地雷达成像的原型系统，该系统已用于一项初步研究，测量志愿者的反射信号。通过检查传感器的机械定位以及微波测量灵敏度来探究该系统的性能。为深入了解反射信号的测量，对一个简单仿体的模拟和测量进行了比较，并结合系统灵敏度进行了讨论。最后，描述了对一名志愿者的成功扫描。
