A magnetic resonance imaging (MRI) gradient coil assembly includes a substrate and first hollow conductor coil. The substrate has a surface. The first hollow conductor coil includes a first coiled portion and a first end run portion joined by a first eye lead portion. The first coiled portion defines a series of increasing radius loops disposed on the surface of the substrate, with an outer loop of the first coiled portion defining a coiled portion boundary. The first eye lead portion is disposed in a central portion of the first coiled portion. The first end run portion extends continuously from the first coiled portion via the first eye lead portion beyond the coiled portion boundary.

Systems and methods for MRI continuous gradient coils

A connection system includes a connector electrically connected and fixedly secured to a gradient coil assembly of a magnetic resonance imaging device, a cable block fixedly secured to a magnet of the magnetic resonance imaging device substantially above the connector, and a cable having a first end electrically connected to the cable block and a second end received by the connector and forming an electrical connection between the connector and the cable block.

Connection system and method

A magnetic resonance imaging (MRI) device includes an inner gradient coil assembly proximate a patient positioning area, an outer gradient coil assembly proximate a magnet assembly, and a damping layer sandwiched between the inner and outer gradient coil assemblies.

Acoustically damped gradient coil

The present invention provides for a cooling system for circulating a coolant to cool the patient bore. In one embodiment, that patient bore consists of two concentric cylinders separated by spacers running either longitudinally or helically. In another embodiment of the present invention, fluid may be passed either helically or longitudinally through tubes bonded to the outer diameter of the patient bore such that the parts of the bore that are exposed to the patient are directly cooled. In a third embodiment, the RF coil could form part of the patient bore, with the helical or longitudinal fluid channels surrounding the patient bore.

A self-shielded gradient coil assembly for an MR imaging system has inner and outer gradient coil windings disposed in coaxial relationship and defining a hollow annular space therebetween. Inner and outer helical cooling tubes are affixed to the outer and inner surfaces of the inner and outer gradient coil windings, respectively, by a thermally conductive epoxy, and a concrete filler material substantially fills the remaining hollow annular space. The concrete filler material may be poured into the hollow annular space to fill the space, or a pre-formed hollow concrete cylinder may be inserted coaxially into the space, defining remaining inner and outer annular volumes which are then filled with a thermally conductive epoxy bonding together the inner and outer gradient coil windings, the cooling tubes and the hollow concrete cylinder.

Nb--Sn precursor articles are described that include a Nb alloy article that is at least partially coated with a layer of a Sn alloy, such as a Sn--Cu alloy. The precursor articles described herein have a controlled concentration of the impurity elements As and S in the Sn alloy layer. The concentration of these elements in the Sn alloy layer is less than or equal to 50 ppm by weight. This invention also describes a method for making Nb--Sn precursor articles having a controlled concentration of As and S impurities.

The invention is related to a continuous coating apparatus for applying molten metal on a metal sheet or tape. The apparatus has an annular cylinder having an open lower section extending to a substantially closed upper section. An axle is mounted in the lower section normal to the cylinder axis, and a spool is mounted on the axle. A pair of tubes are mounted parallel to the cylinder axis inside the cylinder on oppositely facing surfaces so that a tape extending around the spool towards the upper section extends through the tubes.
