Abstract

In this study, the 3D mammography geometry is considered to detect breast cancer based on the electrical impedance tomography. The finite element method formulation of the forward 3D electrical impedance tomography model with complete electrode model is considered for the rectangular mammography geometry. For the discretization, Galerkin method is adopted on linear tetrahedral elements. The regularized one-step Gauss-Newton method is employed as the inverse solver. A test phantom designed specifically to resemble the shape of compressed breasts is used with ACT4 measurement system. The numerical simulation and extensive experimental results are shown to illustrate the proposed method.
