This work presents the feasibility of Bloch-Siegert (BS) frequency encoding for magnetic resonance (MR) applications requiring a simultaneous transmit and receive system. RF frequency encoding technique is referred to receiving MR signal while existing one offset-field radiation, which can be considered as a radio frequency interference(RFI). A prototype was built demonstrating first MR experiment and preliminary data using this method. Our system is currently a research technology with the goal of generating a low-field and point-of-care medical imaging system using novel RF encoding.
