Abstract

A two-dimensional electrical impedance tomography problem in the case of piecewise-constant electrical conductivity, taking two known values, is considered. It is required to determine the boundary between regions with different conductivity. The initial information for solving the problem consists of several pairs of current and voltage distributions on the outer boundary of the body. A numerical method for determining the unknown boundary is proposed, and the results of computational experiments are presented.

在分段恒定电导率情况下确定电阻抗断层扫描问题中不均匀边界的一种数值方法

摘要

考虑采用两个已知值的分段常数电导率情况下的二维电阻抗断层扫描问题。需要确定不同电导率区域之间的边界。解决问题的初始信息包括身体外边界上的几对电流和电压分布。提出了一种确定未知边界的数值方法，并给出了计算实验的结果。
