A gradient coil for a magnetic resonance imaging apparatus (10) includes a
primary coil (16) defining an inner cylindrical surface (60), and shield
coil (18) or coils defining a coaxial outer cylindrical surface (62).
Coil jumps (74)connect the primary and shield coils (16, 18). The coil
jumps (74) define a non-planar current-sharing surface (64) extending
between inner and outer contours (66, 68) that coincide with the inner
and outer cylindrical surfaces (60, 62), respectively. The coil (16, 18,
74) defines a current path that passes across the current sharing surface
(64) between the inner and outer contours (66, 68) a plurality of times.
Optionally, some primary coil turns (70) are electrically interconnected
to define an isolated primary sub coil (P2) that together with a second
shield (S2, S2', S2'') enables a discretely or continuously selectable
field of view.
