In this abstract, we developed and evaluated an improved stack-of-stars (SOS) sampling strategy that can efficiently sample 3D k-space and reduce streaking artifacts. Compared with conventional SOS sampling strategies that collect the same radial angle for every slice, proposed method rotates the spokes in a golden-angle manner along the slice direction, which modifies the aliasing pattern resulted from k-space under-sampling. With either gridding reconstruction or more advanced methods, proposed rotated SOS sampling strategy provides improved image quality with reduced streaking artifacts and better delineation of fine structures.
