Abstract:
A method of magnetic resonance imaging comprising:(a) exciting magnetic resonance in an image region; (b) after each excitation of magnetic resonance, causing a magnetic resonance echo during which a magnetic resonance echo signal is generated; (c) applying a plurality of phase encode gradients such that the resultant magnetic resonance echo signals are phase encoded in accordance with the phase encode gradients; (d) collecting a non-rectangular central portion of the magnetic resonance echo signal surrounding a central frequency; (e) collecting a non-rectangular side portion of the magnetic resonance signals between the central portion and one extreme of a resonance signal bandwidth; (f) generating a phase correction data value set from at least a portion of the central and side portion data value sets; (g) generating a conjugately symmetric data value set from at least a portion of the central and side portion data value set; (h) phase correcting the conjugately symmetric data value set in accordance with the phase correction data value set; (i) combining the central portion, side portion, and conjugately symmetric data value sets to produce a combined data set; and, (j) transforming the combined data set into an intermediate image representation.
