3D centric ordering and spherical coverage. The 3D stack-of-rings can be acquired with centric ordering in all three spatial dimensions and supports spherical coverage in 3D k-space for additional time-savings while maintaining isotropic spatial resolution. The central region of k-space is covered very rapidly using only a small fraction of the full set of samples, thus ensuring that the intended contrast is captured very effectively at a desired point in time.
