Abstract
A nuclear magnetic resonance imaging apparatus and an imaging method. A slice gradient magnetic field and a first radio frequency (RF) pulse magnetic field or the first and second RF pulse magnetic fields are applied to an object so as to selectively excite nuclear spins of the object and to generate echo signals by the application of the magnetic fields. The echo signals are measured by applying to the object a read gradient magnetic field whose polarity inverses continuously at least a plurality of times. A plurality of first RF pulse magnetic fields are generated in one pulse sequence. These RF pulse magnetic fields excite the nuclear spins of a plurality of different slices, and a plurality of different slices are selected. Sets of a plurality of echo signals from different slices are defected whenever the read gradient magnetic field is applied.
