ABSTRACT:
Registration of images includes rotational and translation correction. Rotational correction includes estimating a rotational-correction angle by polar K-space cross-correlation. K-space regridding is used to rotate an image by the estimated correction angle. Translational correction is obtained by K-space phase-plane conjugation.
