ABSTRACT:
A gradient coil system for a nuclear magnetic resonance tomography apparatus has a set of saddle coils disposed on a first cylindrical surface for generating the x-gradient, and a set of saddle coils disposed on a second, separate cylindrical surface for generating the y-gradient. The saddle coils in each set include three sub-coils having predetermined ampere turns, and formed by cable conductor wound exclusively by convex turns arranged in the same cylindrical surface. A middle coil of the three sub-coils has an arced portion facing the z=0 plane in an x-y-z coordinate system which approximates an arc of an ellipse.
