Systems and methods for common mode traps in MRI systems

A common mode trap assembly for a magnetic resonance imaging (MRI) system, comprising:

• a central conductor with a length and configured to transmit a signal between an MRI radio frequency coil and a processing element of the MRI system;
• and
• a plurality of common mode traps extending along at least a portion of the length of the central conductor, the common mode traps configured to provide an impedance to reduce transmitter-driven currents of the MRI system, wherein each of the common mode traps comprises a second length and includes a plurality of conductor pairs, each conductor pair of the plurality of conductor pairs comprising a first conductor and a second conductor counterwound around the central conductor.

A method for providing a transmission cable for a radio frequency (RF) coil of a magnetic resonance imaging (MRI) system, comprising:

• providing a central conductor of a length and configured to transmit a signal between the RF coil and a processing element of the MRI system;
• and
• positioning a plurality of common mode trap conductor pairs around the central conductor along at least a portion of the length of the central conductor, wherein the plurality of common mode trap conductor pairs are distributed symmetrically about the central conductor, wherein each common mode trap conductor pair includes a first common mode trap conductor wrapped in a spiral in a first direction about the central conductor along the portion of the length of the central conductor, and a second common mode trap conductor wrapped in a spiral in a second direction opposite to the first direction about the central conductor along the portion of the length.
