Abstract :
We propose a novel microwave imaging technique for biological tissue, both with and without bone support. The imaging technique is based on the Field Mapping Algorithm (FMA), which is a direct inversion method requiring neither optimization nor iterative procedures. Conventional microwave tomography is based on optimization strategies which require large modeling libraries for the generation of effective start-up configuration seeds leading to successful forward solutions for internal electric parameters, such as conductivity and dielectric permittivity. Knowledge regarding the spatial distribution of these latter two parameters should be regarded as synonymous with internal image formation. The associated computations are then of necessity intensive as to both execution time and CPU demands.
