Patent ID: 7141980

Claim:
An apparatus for enabling operation of adjacent coil loops with a magnetic resonance (MR) system, the apparatus comprising: (a) a correction network interconnecting the coil loops for enabling both concurrent and separate operation of the coil loops, said correction network including: (I) an input network for each of the coil loops, each of said input networks including a balun and an active decoupling circuit with said active decoupling circuit thereof interconnecting the coil loop corresponding thereto and said balun corresponding thereto and said balun thereof for linking said input network to the MR system, said active decoupling circuits capable of being (A) activated concurrently and thereby disable both of the coil loops during a transmit cycle of the MR system, (B) deactivated concurrently and thereby enable each of the coil loops to receive MR signals from tissue within a field of view thereof during a receive cycle of the MR system and (C) deactivated/activated separately and thereby enable either one but not both of the coil loops to receive MR signals from the tissue within the field of view thereof during the receive cycle of the MR system; and (II) an isolation circuit interconnecting the coil loops for substantially canceling mutual inductance between the coil loops while the coil loops are enabled concurrently.
