摘要：
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.
