Simultaneous reconstruction of outer boundary shape and conductivity distribution in electrical impedance tomography

The aim of electrical impedance tomography (EIT) is to reconstruct the admittance distribution inside a body from boundary measurements of current and voltage. In this work, the need for prior geometric information on the measurement setting of EIT is relaxed by introducing a Newton-type output least squares algorithm that reconstructs the admittance distribution and the object shape simultaneously. The functionality of the technique is demonstrated via numerical tests with experimental data.
