监测缺血性脑水肿的新方法——脑电阻抗地形图法

Examining brain oedema through brain electrical impedance topographic mapping

脑电阻抗的变化与脑水肿、脑梗塞有极大的关系,文中提出了脑电阻抗地形图应用在脑水肿检测的新方法。介绍了脑电阻抗地形图的硬件结构、脑阻抗网络拓扑结构,以网络中的三角形单元为基础,详细讨论地形图的绘制处理算法。对脑水肿病人,进行了数据测取,并通过计算机形成阻抗地形图。从对病情变化病例的比较分析和稳定病人数据的重复性已经验证了这种方法的可行性。

Change of Brain Electrical Impedance has great relations with brain oedema and brain block, a new method of Examining Brain Oedema through Brain Electrical Impedance Topographic Mapping(BEITM)is reviewed. Network topology structure that used in BEITM are also presented. According to topology, we discuss the drawing algorithm that based on triangle element. Some patients have been measured to make clinical data, according to this data Brain Electrical Impedance topographic come into being by computer at last, functional imaging has been implemented. Clinical case analysis compared with change state of an illness and repeatability of steady patient's data has proved the method is feasible.
