A comparison of different methods for the gradient evaluation in the inverse problems of the impedance tomography

conference paper

English

The standard approach for the evaluation of the gradient during the optimization process in the impedance tomography is based on the inverse of the global admittance matrix utilizing certain iterative procedure of nodal voltages. In this paper the benefit of the gradient evaluation by different position of the grounding node on the mesh are compared.
