Figure 6: Spin-echo images of (top) a phantom (TR/TE  =  4000/100 ms, BW 789 Hz/pixel, FA ${50}^{\circ }$, 1 mm slice) and (bottom) a human brain in vivo (TR/TE  =  4000/15 ms, BW 401 Hz/pixel, FA ${70}^{\circ }$, 1 mm slice) reconstructed from noisy data ($96\times 96$ samples, $288\times 288$ reconstruction matrix) using zero-padding (zero), the proposed extrapolation method (TV2), and the proposed method combined with denoising (TV2dns). Arrows  =  truncation artifacts.
