ABSTRACT:
A novel method of magnetic resonance imaging is disclosed, in which a single high-frequency magnetic field signal synthesized from a plurality of high-frequency components associated with a plurality of slice sections respectively is applied to a subject to excite the slice sections at the same time, and a phase encode pulse is applied in the direction perpendicular to a slice section. Information corresponding to the position of a slice section is applied to the phase of an excited spin and a measurement signal is subjected to Fourier transformation thereby to produce a data corresponding to each slice section. The phases of a plurality of high-frequency components of a high-frequency magnetic field signal are controlled to be in a predetermined relationship to each other at a predetermined timing.
