Comparison of reconstruction results for a radially encoded Shepp-Logan phantom using Kaiser-Bessel gridding method and NUFFT method. Both methods use μ = 2 and q = 4 are used. (a) Difference image between DFT reconstruction and conventional KB reconstruction. I−Ikb. (b) Difference image between DFT reconstruction and cosine LS-NUFFT reconstruction. I−Inucos. (c) Difference image between DFT reconstruction and KB LS-NUFFT reconstruction. I−Inukb.
