Abstract:
A coil for generating an RF magnetic field gradient, said coil comprising:a pair of electrically conductive ring elements separated in a longitudinal direction, each said ring element disposed on an X-Y plane; and at least three electrically conductive elongated members extending in said longitudinal direction and interconnecting said ring elements at junctions which are spaced circumferentially along each of said rings, said at least three electrically conductive elongated members disposed asymmetrically about an X axis of said X-Y plane, said at least three elongated members comprising a center strip and a pair of flanking strips, said pair of flanking strips being disposed diametrically opposite each other with respect to said ring elements, said center strip being disposes at equidistance from said pair of flanking strips, wherein a non-uniform RF field is generated by said at least three electrically conductive elongated members within said coil.
