Abstract : Hepatic steatosis, commonly known as fatty liver disease, is one of the most prevalent liver disorders worldwide. This study investigates the potential of microwave-based diagnostic techniques for observing and analyzing different grades of hepatic steatosis. A microstrip patch antenna (MPA) operating at 5 GHz is employed for both transmission and reception of microwave signals. A human torso model, along with a liver phantom, is simulated using the corresponding dielectric parameters for the selected frequency. The results demonstrate that the presence of fat in liver tissue can be identified based on differences in microwave interaction, as fatty tissue exhibits lower dielectric permittivity compared to healthy tissue. The demonstrated technique can thus predict the stage of Hepatic Steatosis, whether the tissue is healthy or having mild, moderate or severe Steatosis. These findings confirms that the microwave technology can be used as a promising and evolving approach for medical imaging and diagnosis, with significant potential advantages over traditional imaging modalities.
