The structure of the proposed numerical microwave tomography (MWT) approach for bone analysis: a numerical modeling of a cross-sectional MRI-derived image to generate an anatomically realistic finite-element (FE) model; b calculating the synthetic data (scattered electric field values) at the antennas; c an initial image of the object-of-interest (OI) reconstructed blindly; d several image enhancements techniques were used to better enhance bones reconstruction; e bone monitoring following an expert-eye approach to detect variations in bone volume fraction (BVF) as variations in the corresponding dielectric properties
