摘要： A superconducting magnetic resonance imaging magnet assembly is provided. The assembly includes an axial imaging bore to receive patients and a coil housing surrounding the axial bore. A main magnet coil assembly is disposed within the housing. The main magnet coil assembly includes a plurality of main magnet coils to produce a magnetic field. At least three pairs of superconductive coils are provided. In one aspect, each of the coils in at least one of the pairs comprises a superconductor wire carrying an electric current in a direction opposite to the direction of current carried by the coils of another of the superconductive pairs. The superconductor wire comprises a superconductor core and a stabilizer having a channel. The wire is wound so that the channel has a radially outward facing opening. In another embodiment, low-aspect-ratio coils are used for at least one of the pairs of superconductive coils with the outer diameter coil portion comprising a superconductor core and a stabilizer channel having a radially outward facing opening.

摘要： A new method for forming a joint between a molybdenum-based alloy structure and a structure formed from a more ductile alloy is disclosed. The method involves the solid-state bonding of the two structures, which can be carried out by a variety of techniques, such as inertia-welding or explosive-welding. The molybdenum-based alloy may be a TZM-type material, while the more ductile alloy may be tantalum-based, niobium-based, or nickel-based, for example. This method is especially useful in the manufacture of x-ray devices, such as those which include rotary anode assemblies. As one illustration, the method can be used to provide a very strong joint between a target formed from a molybdenum alloy and an insert formed from a tantalum alloy. Related x-ray assemblies are also described.

摘要： An improved high performance x-ray system having a rotating anode therein which includes an improved target/stem assembly comprising a metallic target and a large bore, thin-walled tubular metal stem which, when connected to a rotor body assembly, provides a rotating x-ray tube anode assembly is disclosed. An insert of an alloy, for example, tantalum alloy, is placed between the target layer and the large bore, thin-walled tubular niobium or niobium alloy stem and then bonded thereto to produce a composite x-ray tube target/stem assembly. The target/stem assembly is then connected to a rotor body assembly by fasteners, preferably threaded, to produce a rotating anode assembly having high bond strength that provides acceptable balance during x-ray tube operations.
