Abstract
A radio frequency magnetic field is applied to a sample or object to be examined which is placed in a static magnetic field and oscillates periodically, and nuclear magnetic resonance signals are generated from the sample. The NMR signal is transformed to a signal having a form wherein a still image component and an artifact component resulting from the periodic oscillation, that are contained in the NMR signal, are mutually separated, and then processing is applied to the signal thus transformed so as to remove the artifact component therefrom. Inverse transform to the transform described above is applied to the signal thus processed.
