Permittivity and Conductivity Estimation of Biological Scenarios via 3D Microwave Tomography

The estimation of the effective electrical properties of biological tissues is relevant to different medical applications, ranging from hyperthermia treatment planning to dosimetry. In this contribution, we introduce a novel inverse scattering approach to cope with this problem. This latter is relevant to microwave tomography and is herein formulated in 3D geometry. More in details, the procedure performs the inversion of measured fields scattered by the investigated biological scenario by taking advantage from the spatial priors derived from segmented medical images and conveniently representing the unknown electrical properties.
