Abstract
A method of fabricating a coil for a magnetic resonance imaging magnet is disclosed. The method includes providing a plurality of windings each having an axis. A conductor is arranged in a plurality of turns extending in a spiral between the inner end and the outer end of the windings. The turns of each outward winding and inward winding are arranged so that a point moving along the turns in a first direction of rotation about the axis of the outward winding moves from the inner end towards the outer end, and the outer end towards the inner end, respectively. The method further includes superposing the spiral windings one above the other so that the windings are substantially coaxial with one another and electrically connecting the windings in series with one another.
