Theory and Development of Electrical Impedance Tomography Technology

  • 摘要: 介绍了一种新的图像重建技术——电阻抗成像(EIT)技术.它根据物体内部不同物质的导电参数(如电阻率、电容率)的不同,通过对物体表面电流、电压的施加及测量来获知物体内部导电参数的分布,进而重建出反映物体内部结构的图像.作为一个数学物理反问题,EIT技术具有其本身的特点和难点,因而目前还处于探索性研究阶段.本文在EIT数学物理模型基础上对整个EIT技术作了较为全面的介绍,包括理论原理、技术上的难点、系统分析、以及目前国际国内的研究现况和研究方向.通过对ACT3的介绍,对EIT系统的具体实现也做了简要分析.
