Processing Techniques to Improve Microwave Images for Biomedical Applications

This paper deals with the improvement of the quality of images obtained at 2.45 GHz, by means of a planar microwave camera for biomedical applications. The results provided by standard spectral techniques, classically used for diffraction tomography reconstructions, are shown to be significantly improved by different processing techniques. The particular case of human hand imaging is presented for its clinical interest in the early diagnostic of fibrosis after accidental irradiations.
