Abstract :
In electrical impedance tomography (EIT), cross-sectional resistivity distribution is reconstructed using current and voltage measurements made from the boundary. In this paper, a novel adaptive mesh-grouping scheme is presented to enhance the spatial resolution of the Gauss-Newton algorithm in two-phase fields. Experimental results are provided to illustrate the effectiveness of the proposed scheme.
