PSF analysis for the sufficiently sampled scenario: (a) Schematic for sufficiently sampled Cartesian and radial sampling patterns with the same readout resolution; Panels (b1) and (c1) show the absolute value of the PSFs for Nyquist-sampled Cartesian and radial acquisitions, respectively (with NS=256 samples per readout and a fixed FOV of [-L,L]); Panels (b2) and (c2) are 1D cuts of the respective PSFs along the y axis (same as the cut along x axis).
