An electromagnetic radio wave medical imaging system including: one antenna; transmission, receiving, receiving computing electronics, where the transmission electronics are structured to transmit an electromagnetic-wave having an Orbital Angular Momentum wave-front(OAMw-f) thru the one antenna towards a target, where the OAMw-f includes a vortex-region, where the receiving computing electronics are structured to form a signal from a return wave of the electromagnetic-wave, the system is designed to operate at a near field electromagnetic-wave and as an electromagnetic radio wave medical imaging system, the system is structured to operate in a first phase at a first resolution to identify at least one area of concern within the target, and is structured to operate in a second phase using the electromagnetic-wave having the OAMw-f at a second resolution higher than the first resolution, the second phase is directed to image the at least one area of concern identified in the first phase.
