摘要
Systems and methods for simultaneous radio frequency (“RF”) transmission and reception for nuclear magnetic resonance applications, such as magnetic resonance imaging (“MRI”) are described. The system includes a simultaneous transmit and receive (“STAR”) control system that compensates for the effects of load changes in a radio frequency (“RF”) coil due to the inevitable motion of living subjects (e.g., from subject motion, respiration, swallowing). The system also maintains a high transmit-receive isolation, even when scanning a subject using a continuous RF broad band sweep excitation.
