Abstract
In this paper, electrical impedance endotomography (EIE) is studied using the sensitivity matrix method. Due to the ill-posedness of the inverse problem, the truncated singular value decomposition (TSVD) method and Tikhonov regularization are applied to solve the inverse matrix respectively. Studies are on 2D model and the simulation results show that sensitivity matrix algorithm is efficient and effective in finding the lesion area in EIE.
