Abstract
This work presents the feasibility demonstration of an automatic RF leakage canceler for magnetic resonance imaging (MRI) applications that require a simultaneous transmit and receive (STAR) system. The automatic system with wireless control enables a radiofrequency (RF) coil to achieve greater than 40 dB decoupling between transmit and receive ports in 900 ms. The system stability and noise contribution to MR images were evaluated. To demonstrate feasibility of this approach, MR images were acquired by transmitting an RF excitation pulse and acquiring an MR receive signal simultaneously on a 4-tesla (T) MRI scanner.
