电阻层析成像(ERT)中的一种新的物理模型

A New Model in Electrical Resistance Tomography

在电阻层析成像技术中 ,目前国内外广泛采用电流源激励 ,电压检测方式。本文在深入研究该模型特征的基础上 ,提出了一种新的物理模型 ,两种物理模型相互对照 ,这种新模型具有许多显著的优点 ,通过初步的仿真研究 ,形成的图像令人满意。

At present,the common model in Electrical Resistance Tomography (ERT) is a constant current source power at two adjacent electrodes and voltage measured on other electrodes. In this paper,a new model is introduced.Comparing the two models,the new model presents many advantages.Result of the reconstruction figures is desirable by computer simulation.
