k-t aliasing. With an appropriate undersampling design (a) in a FPP series, the distribution of the point spread function (b) can be predicted. This gives knowledge of how the true object signal in x-f space (c) aliases. Modelling of this predicted overlapping through training data can allow these signals to be separated and therefore permits greater undersampling factors. Reproduced from [76]
