Figure 6: Spin-echo images of (top) a phantom (TR/TE  =  4000/100 ms, BW 789 Hz/pixel, FA 5 0 ∘ , 1 mm slice) and (bottom) a human brain in vivo (TR/TE  =  4000/15 ms, BW 401 Hz/pixel, FA 7 0 ∘ , 1 mm slice) reconstructed from noisy data ( 9 6 × 9 6 samples, 2 8 8 × 2 8 8 reconstruction matrix) using zero-padding (zero), the proposed extrapolation method (TV2), and the proposed method combined with denoising (TV2dns). Arrows  =  truncation artifacts.
