In this article, we present two reconstruction methods intended to be used for
conductivity imaging with data obtained from a planar electrical impedance
tomography device for breast cancer detection. The inverse problem to solve is
different from the classical inverse conductivity problem. We reconstruct the
electrical conductivity of a two-dimensional domain from boundary measurements
of currents and interior measurements of the potential. One reconstruction
algorithm is based on a discrete resistor model; the other one is an integral
equation approach for smooth conductivity distributions.
