摘要

本研究介绍了一种使用八个紧凑超宽带（UWB）天线阵列诊断多发性脑肿瘤的方法。利用雷达技术，超宽带单极天线环绕大脑幻像来检测不均匀性。通过商业电磁求解器设计和表征，天线在1-6 GHz频率范围内工作。制作了三维脑和肿瘤模型，实现了基于八天线阵列的微波成像系统。该系统通过分析后向散射信号重构雷达图像，采用延迟和算法进行肿瘤检测。结果表明，该系统能有效识别单个或多个脑肿瘤，测量数据与模拟数据具有较高的相关性。

Development of Microwave Imaging System Using UWB Antenna Array for Inhomogeneity Detection in Human Brain Phantoms

This study introduces a method for diagnosing multiple brain tumors using an array of eight compact ultrawideband (UWB) antennas. Employing radar technology, UWB monopole antennas encircle a brain phantom to detect inhomogeneities. Designed and characterized via a commercial electromagnetic solver, the antennas operate within a 1–6 GHz frequency range. A 3-D brain and tumor phantoms are fabricated, and eight antennas array based microwave imaging system is implemented. The system reconstructed radar-based images by analyzing back-scattered signals, using the delay-and-sum algorithm for tumor detection. Results show the system effectively identifies single or multiple brain tumors, with high correlation between measured and simulated data.
