Impedance tomography seeks to recover information about the internal electrical conductivity of an object by means of voltage and current flux measurements made on its boundary, and so provide a non-invasive, non- destructive imaging technique. The goal of this paper is to provide a method for the approximate recovery of certain types of perturbations of a constant background conductivity. By using methods adapted to the class of conductivities at hand, one hopes to achieve more modest computational loads than more general methods and better continuous dependence of the resulting estimates on the boundary measurements.
