Suppressing loop current of shielded loops at fundamental resonance [PDF]

open access: yesScientific Reports
In magnetic resonance imaging (MRI), arrays of small loop antennas/coils are extensively used for signal reception. In such arrays, the loop current must be suppressed to prevent transmit antennas or other elements in a receive array from being detuned ...
