Popis:	A novel 3D tomographic algorithm for short range cylindrical geometries using UWB frequency range is presented. The algorithm has been applied to breast tumor detection, nevertheless, its non application-specific character permits the use in other applications. The detection capability of the tomographic algorithm is proved through numerical simulations and experimental measurements of canonical and more realistic bodyattached breast phantoms. For the acquisition of the experimental data, a virtual array-based cylindrical measurement setup has been built. At the current stage of development 3 degrees of freedom are available allowing the scanning of bodies with revolution symmetry.
