摘　　要：针对脑组织电阻抗的研究,本文设计了工作频率在10 MHz的单通道硬件电路和试验台,可以分辨电导率介于0.001 s/m到6 s/m的四种不同浓度的NaCl盐溶液,并对模拟正常人脑组织(0.375 s/m)的0.195％NaCl盐溶液目标,给出了初步成像结果。To make further research of brain impedance, we develop the 10MHz single-channel system and its test phantom, which can distinguish the four different kinds of concentration NaCl brine ranging from 0.001 s/m to 6 s/m. And the preparatory imaging result is given by modeling the normal human brain tissue (0.375 s/m) utilizing 0.195% NaCl brine as an object in this paper.
