Novel Microwave Torso Scanner for Thoracic Fluid Accumulation Diagnosis and Monitoring

Abstract Thoracic fluid accumulation is one of the significant and early-stage manifestations of fatal diseases, such as lung-cancer, liver-failure and congestive heart-failure. Currently, computational-tomography (CT)-Scan is the most widely used tool for the detection of thoracic fluid. Yet, it is...
