Ultra-wideband microwave robust Cap on b eamforming imaging system for early breast cancer detection

  • 摘要: 提出了一种基于自主设计小型超宽带天线的微波稳健波束形成(RCB)成像肿瘤检测系统。仿真结果表明，该检测系统对肿瘤反射信号有很高的敏感度。在简单平面模型和核磁共振成像图(MRI)导出模型中进行仿真检测实验，并将天线阵列接收信号用RCB算法进行成像处理。从乳房重构图像中能够得到正确的肿瘤位置及大小信息，实现了平面模型中最小直径3 mm和MRI导出模型中最小直径4 mm的肿瘤检测，证实了该检测系统用于早期乳腺肿瘤检测的可行性。
    Abstract: An ultra-wideband (UWB) microwave robust Capon beamforming imaging system is presented based on a self-designed compact UWB antenna for early breast cancer detection. Simulation results show that the proposed detection system is sensitive to tumor response. Simulated tumor detection experiments are carried out in both simple planar breast model and magnetic resonance imagining (MRI)-derived model using the antenna array. Robust Capon beamforming algorithm is employed to reconstruct the breast image. Successful detection of 3-mm-diameter tumor is achieved in the planar model and the same detection result of 4-mm-diameter tumor is achieved in the MRI-derived model. The right information of the tumor can be obtained from the imaging results, which demonstrates the feasibility of the proposed system in early breast cancer detection.
