Abstract
A. Nachman (1996) proved global
uniqueness for the 2-D inverse conductivity
problem using a constructive method of proof.
In terms of electrical impedance tomography
(EIT), this is an approximate model
assuming that current flows in a 2-D slice of
the 3-D body under imaging.
Based on this proof, Siltanen, Mueller and
Isaacson (2000) presented a new numerical
reconstruction algorithm for EIT that solves the
nonlinear problem directly without iteration.
In the talk the algorithm is extended by
introducing a new regularization scheme.
As numerical examples we present
reconstructions of conductivities from
simlated boundary data containing
simulated noise
