ABSTRACT:
A gradient coil comprising: a pair of gradient coil units disposed so as to enclose a gradient axis, each gradient coil unit including: a gradient coil substrate with a primary coil section, a shield coil section, and first and second return path sections, the primary coil section disposed between the gradient axis and the shield coil section, the primary coil section configured to produce a magnetic gradient field at the gradient axis when conducting an electrical current; the first return path section foldably connected between the primary coil section and the shield coil section, and the second return path section foldably connected between the shield coil section and the primary coil section such that the gradient coil substrate forms a cylindrical surface having a longitudinal axis substantially aligned with the gradient axis; and a plurality of substantially parallel conductive paths disposed across the cylindrical surface in a direction transverse to the gradient axis.
