摘要： A method and apparatus for suppressing electromagnetic fields induced in cables and electronic medical devices by a magnetic resonance imaging (“MRI”) system are provided. The apparatus includes a cable assembly constructed as a conductive wire wrapped around a paramagnetic core. The paramagnetic core may include a tube filled with a paramagnetic material, such as a gadolinium-based solution or a liquid in which iron oxide particles are suspended.
