A magnetic resonance imaging system includes a primary magnet and a
secondary magnet operable to produce magnetic fields within a sample
being imaged. The MRI system further includes at least one RF coil that
is operable to receive electromagnetic frequencies from the sample. The
RF coil is formed from tubing that serves as a cooling conduit through
which flows a cooling fluid provided by a cooling source. The cooling
fluid cools the RF coils to improve imaging of the sample.
