摘要：

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. © 2021, Pleiades Publishing, Ltd.
