Abstract
To correct motion and magnetic field inhomogeneity phase errors, inverting data collecting read gradients Nr and Nr are applied to collect correcting data H (n, ) and H (n, ) corresponding to focused navigation echoes Ne and Ne data collecting read gradients r , . . . , rM which are inverted alternately are applied, and phase encode gradients pdn, p , . . . , pM are applied at inverting, thereby collecting imaging data F (n, ), . . . , F (n, M) corresponding to the focused imaging echoes e , . . . , eM. This sequence is repeated for n= , . . . , N while changing the magnitude of the phase encode gradient pdn, whereby data F ( ) to F (N, M) for filling a k space are collected. Based on the correcting data H (n, ) and H (n, ), the imaging data F (n, ), . . . , F (n, M) are phase corrected.
