A MODEL-DRIVEN APPROACH TO MICROWAVE DIAGNOSTICS IN BIOMEDICAL APPLICATIONS

In this paper, a model-driven approach to microwave diagnostics for bi ological bodies is presented, The approach is developed In the space d omain and is based ore a numerical solution of the equation for the sc alar two-dimensional (2-D) inverse-scattering problem, The aim is to u se ''a prior'' information on the biological body under test (homogene ous along the transverse axis) in order to focus the investigation pro cess on only one Subdomain of the body, with a considerable computatio nal saving, The method requires the numerical computation of the Green 's function for an unpertarbed model of the body In order to apply rec onstruction techniques to a reduced investigation domain, which can be changed inside the body. with a reduction in on-line computation, The paper defines the mathematical formulation for a 2-D TM and presents the reconstructions of some schematized scatterers corresponding to li ving tissues.
