The correction network includes an input network for each coil loop and an isolation circuit. Each input network includes a balun and an active decoupling circuit for interconnecting the coil loop and balun. The balun links the input network to the MR system. The active decoupling circuits are capable of being (A) activated concurrently thereby disabling both loops during the transmit cycle, (B) deactivated concurrently thereby enabling each loop to receive MR signals during the receive cycle and (C) deactivated/activated separately thereby enabling either one but not both loops to receive MR signals during the receive cycle. The isolation circuit interconnects the loops for substantially canceling mutual inductance between them while they are enabled concurrently.
