The use of the extracted prior information using the k-mean clustering algorithm applied to the blind MWT image: a comparison between the original and estimated leg contour; b imaging domain and antennas locations with respect to estimated outermost leg boundary; c, d real and imaginary components of the inhomogeneous background relative permittivity; e, f real and imaginary components of inversion algorithm relative permittivity reconstruction. The red-dotted lines indicate the bones’ actual locations
