Abstract: In an imaging apparatus using the nuclear magnetic resonance, a solenoid coil and a slot-resonator coil are combined with each other so as to constitute a quadrature-phase detection probe.

A favorable probe can be obtained in a vertical-magnetic field type imaging apparatus.

Abstract: A three-dimensional NMR imaging method using phase encoding field gradients along two direction is disclosed. The measurement of an NMR signal is repeated in such a manner that among all combinations of a plurality of magnitudes of gradient prepared for the phase encoding field gradient along one of the two directions and a plurality of magnitudes of gradient prepared for the phase encoding field gradient along the other direction, combinations in which the magnitude of the phase encoding field gradient along the one direction is not larger than a predetermined value, are selected preceding the remaining combinations. A first image reconstruction processing is performed for data trains acquired on the basis of the precedently selected combinations, thereby obtaining a crude image. The crude image is displayed to confirm whether the location of measurement is proper or not.
