| 摘 要： | 针对脑组织电阻抗的研究，本文设计了工作频率在10MHz的单通道硬件电路和试验台，可以分辨电导率介于0．001s/m到6s/m的四种不同浓度的NaCl盐溶液，并对模拟正常人脑组织（0．375s/m）的0．195％NaCl盐溶液目标，给出了初步成像结果。

| Abstract: | 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. |
