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.

Apparatus and method for cryogenically cooling a coil on a magnetic resonance imaging system

A radio frequency coil array () includes at least first () and second () receive coils. A flux pipe () includes electrically connected first () and second () loop coils. The first () and second () loop coils are coupled to the respective first and second receive coils. The flux pipe () reduces mutual inductance between the first () and second () receive coils.

Coil decoupling in magnetic resonance imaging

An apparatus for use in a magnetic resonance examination includes a radio frequency receive coil () and adjustable tuning circuitry () for adjusting the resonant frequency of the receive coil. The apparatus also includes a preamplifier () which amplifies signals generated by the receive coil. An adjustable feedback circuit () alters an effective Q of the receive coil.

Bandwidth expansion in magnetic resonance

A magnetic resonance coil systemallows for the use of modular components and which in one embodiment is particularly well-suited for use with small animals and includes an animal receiving apparatus, a transmit coil module, and a receive coil module. The receive coil moduleincludes a cryogenic receive coil. The coil systemis selectively insertable in the bore of the gradient coil of a magnetic resonance examination system.
