The electrical impedance tomography is a means how to localize inhomogeneities in some bordered homogenous medium when the object under investigation is accessible to the measuring only at specific points of its boundary. In the method various optimization techniques are in use. For their successful application it is useful to determine Jacobian which helps to accelerate an iterative process. In the paper two ways of Jacobian calculation are compared above all from the point of view of the CPU time. Namely, the first method is based on the reciprocity theorem application, the second one then on the direct differentiation of the nodal-analysis matrix equation. Both methods utilize a precomputed properly chosen finite-element mesh, and has been programmed in the Matlab language environment.
