【摘要】:本文介紹了一種用于出血性腦卒中診斷的微波腦部成像仿真。首先利用DebyeⅡ公式對(duì)人體腦組織與血塊的電磁特性進(jìn)行研究,確定成像的微波頻段。在此基礎(chǔ)上進(jìn)行電磁特性仿真的腦部模型構(gòu)建,設(shè)計(jì)一款工作在1.7~4 GHz的超寬帶Vivaldi天線用于微波信號(hào)發(fā)射與接收。Vivaldi天線圍繞腦部模型旋轉(zhuǎn),發(fā)射并接收微波信號(hào)。采用對(duì)稱位置消噪法消除接收信號(hào)的強(qiáng)背景噪聲,利用共焦成像方法進(jìn)行成像。從成像結(jié)果中能夠清晰分辨出出血塊的位置,位置誤差達(dá)到1 cm以下。
