电阻抗层析成象（EIT）系统的研究

本文提出一种新的获取图象重建数据的系统，该系统通过在模型边界的３２个电极上注入多种组合方式的自适应电流，然后测量相应电极上的电压值，再经过特定的算法处理，得到重构图象。同时介绍了系统的数学模型及算法原理。

Study of Electrical Impedance Tomography(EIT)System

This paper presents a system designed to acquire data for the reconstruction ofimages.The system applies adaptive currents at 15 kHz in any desired pattern to 32 electrodes and measures the resulting voltage at each electrode.With some special imagereconstruction algorithm,the reconstructed image can be obtained.The paper also describes the related finite element model and fundamentals of the-reconstruction algorithm.
