微波成像的基础是乳腺正常组织和肿瘤的介电特性的对比。共焦微波成像涉及通过多个天线传输超宽带信号并记录散射信号。然后通过合成聚焦乳房的反射，我们可以从乳房成像。在本文中，我们演示了使用不同数量的天线布置在三个维度上检测 10 毫米和 5 毫米肿瘤的可行性。提出了两种半球形阵列模型。提出了一种用于 3D 图像制作的图像形成算法。通过半球形排列可成功检测 10 毫米和 5 毫米肿瘤。还探讨了不同乳房大小对肿瘤检测的影响。 (C) 2015 年 Wiley 期刊公司。
Basis of the microwave imaging is the contrast in dielectric properties of breast normal tissue and tumor. Confocal microwave imaging involves transmitting an ultrawideband signal through number of antennas and records the scattered signals. Then by synthetically focusing reflections from the breast, we can make image from breast. In this article, we demonstrate the feasibility of detecting 10- and 5-mm tumors in three dimensions with different antenna arrangements with different number of antennas. Two models of hemispherical array are presented. An image formation algorithm is presented for 3D image making. Successful detection of 10- and 5-mm tumors are achieved with the hemispherical arrangement. The influences of the different breast sizes for tumor detection are also explored.
