Patent ID: 7719274

Claim:
A method of obtaining a magnetic resonance image in which streak artifacts are corrected, the method performed by a magnetic resonance imaging apparatus, the method comprising: acquiring magnetic resonance image information {tilde over (S)} n M (k RO ) by gradient echo planar imaging (EPI) under a state that a phase-encoding gradient magnetic field is applied; acquiring reference information {tilde over (S)} n R (k RO ) by spin echo EPI under a state that the phase-encoding gradient magnetic field is not applied; calculating a phase value of the reference information e iΦ n R (x) by performing a one-dimensional Fourier transformation on the reference information; calculating a non-linear phase function e −iΦ n R (x) by converting the sign of the of phase value of the reference information; calculating corrected image information in a Fourier domain {circumflex over (P)} n M (x) by performing the one-dimensional Fourier transformation on the image information and multiplying the resulting Fourier transformed image information by the non-linear phase function of the reference information in the Fourier domain; and obtaining the streak corrected magnetic resonance image by performing a one-dimensional Fourier transformation on the corrected image information.
