Abstract: A system for inductively communicating signals in a magnetic resonance imaging system is presented. The system includes first array of primary coils configured to acquire data from a patient positioned on a patient cradle. Furthermore, the system includes a second array of secondary coils operatively coupled to the first array of primary coils. Moreover, the system includes a third array of tertiary coils disposed at a determined distance from the second array of secondary coils. In addition, the system includes a tuning unit operatively coupled to the third array of tertiary coils by a cable having a quarter-wave electrical wavelength and configured to control the first array of primary coils through impedance transformation, where the second array of secondary coils is configured to inductively communicate the acquired data to the third array of tertiary coils.
