ABSTRACT:
A method and an apparatus for nuclear magnetic resonance imaging, using a shim coil which adjusts a static magnetic field to improve the homogeneity of the static magnetic field, capable of determining an appropriate amount of current to flow through the shim coil in accordance with a nuclear magnetic resonance signal due to water, in order to achieve an accurate adjustment of the homogeneity of the static magnetic field. The determination of the amount of current may be made by selecting current parameters for which a half-width of the nuclear magnetic resonance signal spectrum due to water is the smallest. The determination of the amount of current may be made by selecting current parameters for which a peak value of the nuclear magnetic resonance signal spectrum due to water is the largest.
