Magnetic resonance angiography with sliding interleaved projection reconstruction (SLIPR) acquisition.
In this paper, we report on the development of a novel multiple thin-slab projection-reconstruction acquisition technique. To eliminate the slab boundary artifact, the slabs are highly overlapped and only a small fraction of the projection view angles are sampled at each slab position. After Fourier transformation in the slice direction, there are sufficient numbers of projection measurements at each slice position to obtain very high resolution MR angiograms. The technique presented has all of the advantages of multiple overlapping thin slab acquisition (MOTSA) with no evidence of slab boundary artifact. J. Magn. Reson. Imaging 1999;10:569-575.
