  • In this paper, a general method for synthesizing the voltage data in electrical impedance tomography is presented. Based on this, a method for eliminating the reciprocity noises in measured voltages is proposed. This method can be used to eliminate the reciprocity noises in measured voltages in any multi-source case. Simulation test shows this method can decrease the noises in measured voltages effectively and can improve the quality of reconstruction image notably.
