| description | PROBLEM TO BE SOLVED: To improve the operational performance of a gradient coil.SOLUTION: A first layer of coil comprises a first plurality of turns of wires which spirals in a substantially parallel trajectory along an inner side wall of a cylindrical substrate in a first helical direction from an upper edge of the cylindrical substrate to a lower edge thereof. The first plurality of turns of wires traverse the substrate and then spiral along an outer side wall of the cylindrical substrate in a second helical direction to the upper edge, so that each turn of wire in the first plurality of turns of wires circles along the side walls of the cylindrical substrate and includes a first portion wound along the inner side wall and a second portion wound along the outer side wall. |
