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 first conductor and a second conductor counterwound around the central conductor, wherein the first and the second conductors are radially spaced a first distance from the central conductor at first and second ends of the second length, wherein the first and the second conductors are radially spaced a second distance larger than the first distance from the central conductor at a midpoint of the second length, and wherein a radial distance of the first and the second conductors tapers from the second distance at the midpoint of the second length to the first distance at the first and the second ends of the second length.
