Originální abstrakt

An electrical impedance tomography (EIT) is instrumental to localize inhomogeneities in some bounded homogenous medium. An object under investigation is accessible to be measured only at specific points of its boundary. On the basis of measured data the inner structural changes are estimated. In the EIT method various optimization techniques are in use. For their successful application it is often useful to compute absolute sensitivities serving to create Jacobian which can help to accelerate an iterative process. In this paper a method based on the reciprocity theorem in conjuction with the finite element method (FEM) is applied to find the sensitivities. Herein, the work is restricted only on a simpler 2D problem.
