我们提出了一个3-D微波乳房成像研究中，我们重建的介电分布的MRI衍生的数字乳房phantomy从模拟阵列测量使用一个封闭的阵列的多频带，小型化贴片天线。该阵列的设计，以克服有关的逆散射系统的不适定性的挑战。我们使用多频配方的扭曲玻恩迭代法成像四个正常组织乳房幻影，每个对应于一个不同的密度类。重建的纤维腺体分布在位置和基本形状上都非常忠实于真实分布。这些结果建立了使用小型化，多频带贴片天线的定量微波乳房成像的封闭阵列的可行性。
We present a 3-D microwave breast imaging study in which we reconstruct the dielectric profiles of MRI-derived numerical breast phantoms from simulated array measurements using an enclosed array of multiband, miniaturized patch antennas. The array is designed to overcome challenges relating to the ill-posed nature of the inverse scattering system. We use a multifrequency formulation of the distorted Born iterative method to image four normal-tissue breast phantoms, each corresponding to a different density class. The reconstructed fibroglandular distributions are very faithful to the true distributions in location and basic shape. These results establish the feasibility of using an enclosed array of miniaturized, multiband patch antennas for quantitative microwave breast imaging.
