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 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.

A method for producing a sterile packaged adhesive hydrogel product by preparing an aqueous mixture of water, a polymer which can be cross-linked by radiation to form a hydrogel, and a cross-linking inhibitor in an amount sufficient to retard the cross-linking of the polymer when the mixture is exposed to radiation; providing the mixture in a predetermined shape or configuration representative of a hydrogel product; enclosing the shaped mixture in a sealed package; and subjecting the package to a dose of radiation sufficient to simultaneously cross-link and sterilize the mixture to provide a sterile packaged adhesive hydrogel product. The invention also is directed to the sterile packaged adhesive hydrogel product formed by this method, as well as the packaged product prior to sterilization. These products include one of the aqueous mixtures described above in a predetermined shape or configuration representative of a reinforced or non-reinforced hydrogel product and a sealed package enclosing the shaped mixture.
