Quasi-Real Time Reconstruction of the Complex Permittivity of Tissue Through Microwave Holography

Quantitative microwave holography is a recently proposed imaging method that offers quantitative reconstruction in a quasi-real time. Since it is a direct inversion method, its utility is limited to weak-scattering problems. The feasibility of microwave holography in tissue reconstruction is studied here. The reconstruction results are promising, suggesting microwave holography is suitable as a linear inversion module within a nonlinear iterative procedure.
