ON ELECTRICAL CAPACITANCE TOMOGRAPHY

介绍了作者在电容ＣＴ重建算法、测量装置方面所进行的工作，并较为详细地介绍一种基于网络理论的新算法，这种算法是将介质分布映射为一个电容网络，网络中的电容值直接与介质分布有关。为了解决从测量电极所测得的电容计算网络内部电容这一逆问题，分析和利用了附加的网络结构约束。将测量过程等效为相应的四端网络，利用迭代方法进行求解，得到了较好的实验结果。

This paper describes a new reconstruction algorithm for Electrical Capaci- tance Tomography. The new algorithm is based on network theory , it maps the dielectric constants of the flow components into a capacitance network. In order to solve the inverse problem of calculating the capacitance's of the network from the measurements, some addi- tonal structure constraints of the network are explored and used. Experimental results are given which confirm the effectively of this algorithm.
