Zusammenfassung
Introduction: The aim of the present study was to assess the basic feasibility of ultra-wideband (UWB) radar in biomedical applications to discriminate tissues with different dielectric constants (ε′+jε′′). This approach is feasible because the dielectric properties of biological tissues are mainly determined by their water content which is relevant concerning the differentiation between cancerous and non-cancerous tissue. Therefore, phantoms with defined dielectric properties were analyzed with a prototype xyz-UWB-scanner. Material and Methods: Nine oil-in-gelatine phantoms were made in a cylindrical mould (6cm…
