The aim of electrical impedance tomography is to reconstruct the electrical conductivity of a body
from boundary measurements of currents and voltages. The problem is strongly illposed. In order
to make it tractable, prior knowledge about the unknown conductivity is required. Let Rd
,
d 2, be a bounded domain which represents the body and Ds = Bs + zs , 1 s m, be
subdomains which neither intersect each other nor touch . The Ds represent inhomogeneities
centered at zs, of size , shape Bs and constant conductivity ks, 0 < ks = 1 < +, s. As a
consequence, conductivity k[·] is assumed to be a function of the type k[x] = [ m
s=1 Ds] +
m
s=1 ks[Ds]. The goal becomes to determine the tuple {, zs, Bs, ks} instead of the precise
