Disclosed is an effective algorithm to correct motion-induced phase error using an iterative reconstruction. Using a conjugate-gradient (CG) algorithm, the phase error is treated as an image encoding function.
Banding artifacts in steady state free precession (SSFP) magnetic resonance imaging (MRI) are reduced by acquiring and combining multiple SSFP images in an augmented matrix where an acquisition vector in k-space is equal to a Fourier matrix of the trajectory on a known distort
Disclosed is a wideband SSFP, wherein a standard balanced SSFP MRI sequence is played with repetition times of alternating lengths, TR and TR.sub.s, where TR.sub.s
