Abstract
In an NMR imaging apparatus, the steady magnetic field is subjected to be deformed. The first shim coil pair is wound on a common bobbin and has a common diameter. The second shim coil pair is wound on the same bobbin and has the same diameter as that of the first shim coil pair. The first shim coil pair corrects homogeneity of the field components of the steady magnetic field having even-numbered higher order terms in the longitudinal axis of the object under examination. The second shim coil pair corrects uniformity of the magnetic field components of the steady magnetic field in the direction perpendicular to the longitudinal axis and also uniformity of the magnetic field components of the first coil pair in the direction perpendicular to the longitudinal axis.
