Abstract
Systems and methods for damping cable common-mode energy in magnetic environments are provided. One system includes a damping arrangement having a transmission line within an electric (E) field environment and an energy damping device formed having a conductive plastic body and positioned adjacent a conductor of the transmission line. The energy damping device is configured to dampen common-mode energy induced within the transmission line by the E field environment.

A damping arrangement comprising:
- a transmission line within an electric (E) field environment;
- and
- an energy damping device formed having a conductive plastic body and positioned adjacent a conductor of the transmission line, the energy damping device configured to dampen common-mode energy induced within the transmission line by the E field environment.
A magnetic resonance imaging (MRI) system comprising:
- an imaging portion having at least one transmit coil;
- a processing portion;
- a system interface interconnecting the imaging portion and the processing portion, the system interface connected to the at least one transmit coil with at least one transmission line;
- and
- an energy damping device formed having a conductive plastic body and positioned adjacent a conductor of the at least one transmission line, the energy damping device configured to dampen common-mode energy induced within the at least one transmission line.
A method for damping common-mode cable currents in an electric (E) field environment, the method comprising:
- providing at least one conductive plastic patch having damping properties;
- and
- positioning the at least one conductive plastic patch at a high voltage node of a transmission line within the E field environment to dampen common-mode energy induced in the transmission line by an E field of the E field environment.
