Wide Band Microwave Imaging of Spherically Shaped Biological Bodies

A new technique for predicting the radially dependent permittivity in spherically shaped biological bodies is presented. It is based on a gener-alization of the well established Fourier transform technique used for reconstructing permittivity profiles in planar stratified media in conjunction with a recently proposed renormalization technique. The later isolates the nonlinearity of the problem in form of a nonlinear algebraic transformation rendering a linear differential equation for an auxiliary reflection coefficient, which can be used in conjunction with a generalized Fourier-Bessel transform to reconstruct the unknown permittivity profile. comparison between the reconstructed and the original profiles has shown excellent agreement within the framework of the required resolution.
