|Microwave tomography deserves attention in biomedical imaging, owing to its potential capability of providing a morphological and functional assessment of the inspected tissues. However, such a goal requires the not trivial task of solving a non linear inverse scattering problem. In this paper, the factors a®ecting the complexity of the inverse problem are exploited to trace guidelines aimed at setting the matching °uid, the frequency range and the number of probes in such a way that the dielectric parameters of female breast tissues can be reliably retrieved.
