Microwave Tomography for Human Body Imaging

A microwave tomography technique for imaging of the human body is presented. It is assumed that the probed structure is a part of a lossy multilayered half-space containing a cylindrical object of arbitrary cross-section and electrical properties. The structure is irradiated by an incident plane wave (TM case). Two-dimensional object function is the induced current distribution in the layer with object. The object function is defined from the backscattered field measurements over the multilayered half-space. Suggested tomographic reconstruction algorithm based on inverse of the derived integral equations relating to Fourier transform of backscattered field data at each excitation frequency to sought object function.
