基于恶性肿瘤与正常乳腺组织电参数的巨大反差，提出了一种用于乳腺小恶性肿瘤检测的超宽带微波图像。本研究采用由9根天线组成的天线阵进行检测。双约束稳健capon波束形成（DCRCB）算法具有较好的稳定性和较高的信噪比（SINR），被用于乳房图像的重建。重建图像成功检测到直径为2mm的肿瘤，证明了DCRCB波束形成算法的鲁棒性。本研究验证了DCRCB成像算法检测乳腺小肿瘤的可行性。
Ultra-wideband (UWB) microwave images are proposed for detecting small malignant breast tumors based on the large contrast of electric parameters between a malignant tumor and normal breast tissue. In this study, an antenna array composed of 9 antennas is applied to the detection. The double constrained robust capon beamforming (DCRCB) algorithm is used for reconstructing the breast image due to its better stability and high signal-to-interference-plus-noise ratio (SINR). The successful detection of a tumor of 2 mm in diameter shown in the reconstruction demonstrates the robustness of the DCRCB beamforming algorithm. This study verifies the feasibility of detecting small breast tumors by using the DCRCB imaging algorithm.
