  • Patent number: 10295629
    Abstract: The present embodiments provide a gradient coil assembly. The gradient coil assembly includes an aluminum wire body, and a copper wire end connected by cold pressure welding to two ends of the aluminum wire body. Using the gradient coil according to a particular embodiment, it is possible to reduce gradient coil weight as well as reduce the thickness of an outer vacuum chamber used for a magnet, thereby reducing the cost of the magnet and gradient coil, and making it less difficult to install and maintain the magnet and gradient coil. There is no problem of oxidation associated with the cold pressure welding of the aluminum wire body to the copper wire ends, so quality defects arising from such oxidation are avoided.

  • Patent number: 9817095
    Abstract: In one embodiment, an electromagnetic shielding of a device is disclosed for a magnetic resonance system. The device is shielded via a conductive layer which surrounds an inner part of the device in such a manner that an electrical current path completely around the inner part can be formed in the layer. The layer is arranged between a housing of the device, surrounding the inner part, and the inner part. In another embodiment, an electromagnetic shielding of a device is disclosed for a magnetic resonance system, wherein the device is shielded via a conductive layer which surrounds the device in such a manner that an electrical current path completely around the device is formed. In this situation, the device having the layer is mounted by way of projections on the magnetic resonance system. Each projection has a contact surface with the layer, at which the respective projection contacts the layer.
