<p>In a apparatus for examining an object by nuclear magnetic resonance to produce images of cross-sectional slices (S1, S2, S3) 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 (S1, S2, S3) during one examination cycle. A plurality of coil pairs (8-1,8-2,8-3) is arranged along the longitudianal axis of the object, and each pair is selectively energized so as to apply to the plurality of slices (S1, S2, S3) one of a plurality of gradient fields (Gz) in conjunction with the steady magnetic field (Ho). A plurality of nuclear magnetic resonance signals may be obtained from a plurality of slices during one examination cycle.</p> |
