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: A gradient coil unit having a peripheral surface enclosing a magnetic gradient axis, and a middle plane substantially perpendicular to the magnetic gradient axis at a middle portion of the gradient coil unit, comprising at least one folded coil which comprises a first set of curved conductors disposed on a first curved surface; a second set of curved conductors disposed on a second curved surface outside the first curved surface and substantially overlapping the first set of curved conductors; and a set of connecting conductors connecting selected curved conductors in the first set with selected curved conductors in the second set; wherein the set of connecting conductors is located at a first side of the middle plane.
