The Shape Reconstruction of Unknown Objects for Inverse Problems

The proposed solution of the inverse problem in the Electrical Impedance Tomography was based on a numerical scheme for the identification of the piecewise constant conductivity. The level set method is a powerful tool for representing moving of stationary interfaces. The representation of the shape of the boundary and its evolution during an iterative reconstruction process is achieved by the level set function. The forward problem was solved by the finite element method. The iterative algorithms are based a combination of the these methods.
