Combination of non-Cartesian data sampling and Compressed Sensing is an obvious way to go for approaching to the best SNR per unit time. Here, the non-Cartesian sampling strategy must incorporate the random sampling paradigm in the most efficient way in multiple facets. In general, one would like to acquire as much signal amplitude as possible per image while achieving as much randomness as possible of the sampling footprint and thus as little coherences in the artifact domain as achievable. However, a third aspect, which has thus far remained unconsidered, is that of induction of Eddy-currents and their effect on the image quality.
