摘要

本文描述了一种微波乳腺癌检测系统,进一步扩展了先前介绍的微波共聚焦成像技术的思想。乳房浸泡在一种液体中,这种液体具有类似于皮肤或乳房组织的电学特性,但损耗小。研究了浸没介质中电阻加载偶极子天线的特性。研究了天线数目和浸泡介质对重建图像的影响。结果表明,两种浸泡介质均可成功检测到直径为6mm的肿瘤,而浸泡在皮肤中的较大肿瘤复发。

Microwave breast cancer detection
A system for microwave breast cancer detection is described, further extending ideas from the previously introduced technique of microwave confocal imaging. The breast is immersed in a liquid with electrical properties similar to skin or breast tissue, but of low loss. The characteristics of resistively loaded dipole antennas in the immersion media are investigated. The influences of the number of antennas and immersion medium on reconstructed images are examined. Results indicate successful detection of 6 mm diameter tumors with both immersion media, and larger tumor returns with the system immersed in skin.
