Medical Imaging System and Method

A microwave imaging system including a microwave antenna array having a transmitting antenna and a plurality of receiving antennas, wherein the transmitting antenna is configured to transmit microwave signals over a range of frequencies so as to illuminate a body part of a patient and wherein the receiving antennas are configured to receive the microwave signals following scattering within the body part. A processor is configured to obtain a set of scattering parameters for the microwave signals over the range of frequencies and, using the scattering parameters, generate an output indicative of the internal structure of the body part to identify a region of interest within the body part. The processor is further configured to classify the region of interest based on a type of tissue therein by analyzing the change of the scattering parameters for the region of interest over the range of frequencies.
