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.
