ABSTRACT:
In a apparatus for examining an object by nuclear magnetic resonance to produce images of cross-sectional slices of the object, it necessarily requires to have "a wait time" so as to repeat the applications of the RF pulses toward a plurality of such slices during one examination cycle. A plurality of coil pairs is arranged along the longitudinal axis of the object, and each pair is selectively energized so as to apply to the plurality of slices one of a plurality of gradient fields in conjunction with the steady magnetic field. A plurality of nuclear magnetic resonance signals may be obtained from a plurality of slices during one examination cycle.
