Abstract

Electrical Impedance Tomography (BIT) is the problem to estimate the conductivity distribution of an object, by injecting currents through its surface and measuring the resulting voltage distribution on the surface. Mathematically, the BIT problem is a nonlinear ill-posed inverse problem with many unknowns. Here we propose a new reconstruction algorithm for BIT, where the interior of the object is described as a set of compartments with unknown position, orientation and size. The unknown parameters are determined by minimizing a cost func
