    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.

    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.

    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.
