  • Patent number: 10877118
    Abstract: The embodiments disclosed herein relate generally to magnetic resonance imaging systems and, more specifically, to the manufacturing of a gradient coil assembly for magnetic resonance imaging (MRI) systems. For example, in one embodiment, a method of manufacturing a gradient coil assembly for a magnetic resonance imaging system includes depositing a first layer comprising a base material onto a surface to form a substrate and depositing a second layer onto the first layer. The second layer may enable bonding between a conductor material and the substrate. The method also includes depositing a third layer onto the second layer using a consolidation process. The consolidation process uses the conductor material to form at least a portion of a gradient coil.

  • Patent number: 10281538
    Abstract: A warm bore cylinder assembly having an outer wall, an inner wall, and a plurality of braces is provided. The outer wall is configured to define an inner exterior portion of a cryostat assembly. The outer wall is generally cylindrical, is made of a conductive material, and has an outer wall thickness. The inner wall is disposed radially inwardly of the outer wall. The inner wall is generally cylindrical, is made of a conductive material, and has an inner wall thickness. The braces extend along an axial direction defined by the outer wall and the inner wall. The plurality of braces are interposed between and join the outer wall and inner wall. The plurality of braces define openings disposed between adjacent braces.

  • Patent number: 10222436
    Abstract: A gradient coil comprises a curved conductor, which is tubular and has a general spiral shape. The curved conductor is formed by a process comprising depositing at least one non-conductive material layer by layer to form a substrate, and coating at least a portion of a surface of the substrate with a conductive material. The substrate has a shape matching with the general spiral shape of the curved conductor. Embodiments of the present disclosure further refer to a method for manufacturing the gradient coil.

  • Patent number: 10126386
    Abstract: 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.

  • Patent number: 9638776
    Abstract: Embodiments of the invention are utilized to improve shimming capability while reducing radial space and the volume required to contain active shim coils by nesting the coils of different degrees and orders inside each other and limiting the azimuthal span of the individual saddle coils. This allows two or more radial shim sets to be combined together in the same layer resulting in a significant radial savings that increases the useable portion of an MRI system.

  • Patent number: 8948841
    Abstract: The present invention relates to a MR tracking method and device. More specifically, the present invention relates to a magnetic resonance tracking method and device, using a magnetic-susceptible object. A magnetic iso-surface induced by the object is selectively excited with a corresponding frequency offset; the magnetic iso-surface is then projected on three axes of a k-space, from which projections the spatial position of the object is calculated.
