ABSTRACT:
A system and method including an apparatus for use in electrically loading RF coils of an MRI system is disclosed. The apparatus includes a polymer interdispersed with an electrically conductive additive such that the apparatus provides the necessary electrical loading of the RF coils for testing and calibration of the MRI system but is free of liquid. Furthermore, the apparatus is capable of providing the requisite electrical load in high magnet magnetic fields without introducing image distortion as a result of standing waves within the apparatus.
