基于雷达的微波乳腺成像是一种基于介电特性差异的有前景的互补成像方法。主要的挑战之一是去除与皮肤相关的压倒性反射。本文提出了一种可应用于真实感三维乳腺模型生成的数据的皮肤减影方法。该方法使用改进的递推最小二乘算法和广义交叉验证技术，将目标天线的蒙皮响应估计为其相邻天线的滤波组合。邻居是基于它们的邻近程度和它们与目标天线的空间相关性来选择的。该方法能够减去皮肤反应并保留肿瘤反应。
Radar-based microwave breast imaging is a prospective complementary imaging method that relies on dielectric property differences. One of the main challenges is removing the overwhelming reflection associated with the skin. In this paper, a skin subtraction method that can be applied to data generated with a realistic three dimensional breast model is presented. The method estimates the skin response of the target antenna as a filtered combination of its neighbors with the use of a modified recursive least squares algorithm and a generalized cross validation technique. The neighbors are selected based on their proximity and their spatial correlation to the target antenna. The method's ability to subtract the skin response and preserve the tumor response is demonstrated.
