A retrospective breathing motion compensation technique for axial MRI with continuously moving table is proposed. Redundant free breathing acquisitions are performed and motion consistent undersampled k-spaces are retrospectively extracted for parallel imaging reconstruction. Compared to a conventional reconstruction from free breathing data artifacts are significantly reduced. Except for increased noise, the achieved image quality is comparable to a reconstruction from a breath-hold acquisition.
