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(More)
Electrical capacitance tomography (ECT) is used to obtain information about the distribution of a mixture of dielectric materials inside a vessel or pipe. ECT has several advantages over other reconstruction algorithms and has found many applications in the industrial fields. However, there are some difficulties with image reconstruction in ECT: The(More)
