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.
