FIG. 2

Cartesian golden-angle sampling scheme used in this work. a: Sampling grid with a circular footprint and temporal ordering of radial half spokes. Only 13 spokes are shown for illustration. The number at the end of each spoke represents a temporal order. Each radial spoke is incremented by the golden angle (≈360°/1.618). Note that the spatial resolution in ky is the same as that in kz, but the FOV in ky is twice as large as the FOV in kz. b: Samples (red dots) chosen along the spokes. Each sample along a given radial spoke was mapped onto its nearest neighboring location in the Cartesian (ky, kz) grid.
