Abstract:
An RF coil comprising:when three mutually orthogonal directions are represented as an x-direction, a y-direction and a z-direction, a first electric path extending in the x-direction;a second electric path parallel to the first electric path in an x-y plane;a third electric path parallel to the first electric path in an x-z plane;a fourth electric path parallel to the third electric path in a plane parallel to the x-y plane, and parallel to the second electric path in a plane parallel to the x-z plane;a fifth electric path connecting the first-fourth electric paths in series so that the first and second electric paths carry respective electric currents in the same direction, and the third and fourth electric paths carry respective electric currents in the same direction opposite to the direction of the first and second electric paths;a sixth electric path extending in the y-direction in the x-y plane;a seventh electric path parallel to the sixth electric path in the x-y plane;an eighth electric path parallel to the sixth electric path in a y-z plane;a ninth electric path parallel to the eighth electric path in a plane parallel to the x-y plane, and parallel to the seventh electric path in a plane parallel to the y-z plane; anda tenth electric path connecting the sixth-ninth electric paths in series so that the sixth and seventh electric paths carry respective electric currents in the same direction, and the eighth and ninth electric paths carry respective electric currents in the same direction opposite to the direction of the sixth and seventh electric paths;wherein the fifth electric path and the tenth electric path do not overlap each other in the z-direction.
