Experimental setup allowing us to choose the number of acquisition samples (from 0 to 144) at each k-space location. Noise is added to 144 copies of the input gold image. These noisy images are then Fourier transformed to create a stack of k-space images with 144 samples available at each k-space location. Note that for the tomato dataset, there is no gold image and the k-space stack comes directly from the 144 scanner acquisitions of the tomato.
