Abstract: A coil system particularly for a wrist for use in an NMR imaging system comprises first and second planar U-shaped rectangular parallel coils. The extended legs of the U-shapes are interconnected to form third and fourth rectangular U-shaped planar coils oriented normal to the plane of the first and second coils to form a rectangular polyhedron coil configuration. A support arrangement for the coils receives a wrist to be imaged and assists in aligning the wrist relative to a body coil of the NMR system. Impedance matching and tuning circuits selectively apply and receive signals from the coils in quadrature.
