电阻抗测量在脑水肿检测中的应用

Electrical Impedance Technology Applied to Examining Brain Edema

生物电阻抗是反映生物组织、器官、细胞或整个生物机体电学性质的物理量,生物电阻抗分析法应用于人体组成成分检测是近年来才发展起来的一种新方法。该技术是利用生物组织与器官的电特性及其变化提取与人体生理、病理状况相关的生物医学信息的一种无损伤检测技术。具有无创、廉价、安全、无毒无害、操作简单和功能信息丰富等特点,医生和病人易于接受。目前无创性脑电阻抗双道检测系统和脑电阻抗地形图系统已经进入了临床实验阶段,非接触磁感应断层成像作为一种新的、更为有效的测量方式被广为关注。

Biological electrical impedance is a physical quantity to reflect electricity character of biological tissue, apparatus, cell or whole organism, which is a kind of new method developed recently to analyze component of body. This technology is unhurt examining method which obtains certain biomedicine information about human body according to electrical character and change of biological tissue or apparatus, has unhurt, cheap, safe, innocuity, operator simple and abundant information etc., is prone to be accepted by doctors and patients. Now unhurt brain electrical impedance double channel examining system and brain electrical impedance topographic mapping system have entered clinical experiment moment, and contactless magnetic induction tomography(CMIT) is taken notice of widely as a more effective examining method.
