A method is provided for manufacturing a coil for a magnet. The method comprises the steps of providing a curved former, and disposing at least one hard-wire electrical conductor around the curved former. The former is initially manufactured in a flat or substantially flat shape, and is then bent into a desired curved shape. The former may be manufactured by moulding, and may be manufactured from a resilient material.

Method of manufacturing a coil for a magnet

This invention is concerned with actively shielded magnetic resonance (MR) devices and more particularly with an improved system which includes only a single former. All the coils of the system those with backward current and those with forward current, can all be wound in a single process on a single former machined during a single installation.

Single former active shield magnets

This invention is concerned with magnetic resonance imaging (MR) systems and more particularly with special MRI systems which enable rotating the data acquisition apparatus of the MRI system. Such systems enables imaging different body parts at a variety of angles; thus providing better diagnostic possibilities.

Magnetic resonance imaging system including an image acquisition

A super-conducting magnet for magnetic resonance imaging systems comprising symmetrically located back-to-back C-frame magnets.

Superconducting magnet with symmetrical plural air gaps

A super conducting magnet system for magnetic resonance systems comprising at least one radiation shield. Temperature sensors, an external refrigeration system and a controller are provided for maintaining said at least one shield at a constant temperature by heating the shield and reducing the heat provided as the refrigerator system wears or by increasing the frequency of the refrigeration cycle as the system wears or both.

Superconductive magnet for magnetic resonance systems

A magnet for MRI systems having a first pair of spaced apart oppositely disposed walls with a first pole piece extending from one wall of said first pair of walls towards a second pole piece extending from the other wall of the pair of walls with an air gap between the first and the second pole pieces. A superconducting coil mounted on at least one of the first and the second pole pieces to generate a magnetic field between the pole pieces with the air gap between the pole pieces large enough for receiving a patient therein fop magnetic resonance imaging purposes; and a second pair of oppositely disposed walls closing said magnetic circuit; there being sufficient room between the walls to enable medical personnel to be between the walls of the second pair of walls and the pole pieces providing substantially complete access to the patient in the air gap.

Magnets providing patient accessibility

A support rod for supporting structures in a cryostat of a magnetic resonance system. The support rod has oppositely disposed stainless steel heads mounted on a glass reinforced plastic rod. The heads have threads on the main body thereof to minimize the length of the heads and thereby minimize heat condition.

Support rod

A hybrid shielding arrangement for solenoid type cryogenic magnets used in MR systems uses both active and passive shielding elements to improve the effective shielding.

Integrated active shielded magnet system

Shim holding independently accessible open cavities are attached to the magnet bore. The holding independently accessible open cavities are arranged in rows and columns to provide readily identifiable locations. The shim holding indpendently accessible open cavities increase the effeciency of shimming to improve the homogeneity of magnets in magnetic resonance systems.

Passively improving magnetic field homogeneity

A superconducting magnet arrangement for magnetic resonance systems including a cryomagnetic dewar containing magnetic coils in a helium vessel surrounded by a nitrogen vessel. A separate support structure is used to support the vessels in the dewar.
