  • 超宽带微波成像技术可作为有效的方法用于乳房早期乳腺肿瘤的检测. 该方法基于乳房组织和肿瘤之间较大的电学特性差异的特点进行成像, 能提供足够的分辨率以及足够的穿透深度. 本文采用时域有限差分方法建立超宽带微波信号在三维乳房组织中传播的模型, 并采用单极德拜模型完成了生物组织色散特性的模拟. 利用8发9收的天线阵列实现微波肿瘤探测, 利用共焦成像算法对乳房组织进行图像重构并进行肿瘤定位. 仿真结果显示共焦成像算法能够实现最小直径3 mm的肿瘤的检测, 同时证实了超宽带微波成像技术应用于早期乳腺肿瘤检测的有效性.
    Ultra-wideband (UWB) microwave imaging technology can be used as an effective method of detecting early breast cancer, which is based on the difference of the electrical characteristic between normal breast tissues and tumor. The method can provide both the sufficient resolution and the adequate penetration depth in the breast. In this paper, the finite difference time domain method is employed to simulate the microwave propagation in three-dimensional breast tissue. The single pole Debye model is used to approximate the real electrical properties of the breast organism. The antenna arrays made up of 8 emitters and 9 detectors are performed for the detection. The confocal imaging algorithm is employed for the reconstruction of the breast tissue and location. The tumor information displayed in the reconstructed breast image verifies the correctness of the confocal imaging algorithm and the effectiveness of the UWB microwave imaging technique applied to the early breast cancer detection.
