Suppression of MRI Truncation Artifacts Using Total Variation Constrained Data Extrapolation
Figure 6
Spin-echo images of (top) a phantom (TR/TE = 4000/100 ms, BW 789 Hz/pixel, FA ,
1 mm slice) and (bottom) a human brain in vivo (TR/TE = 4000/15 ms, BW 401 Hz/pixel, FA ,
1 mm slice) reconstructed from noisy data ( samples, reconstruction matrix) using zero-padding
(zero), the proposed extrapolation method (TV2), and the proposed method
combined with denoising (TV2dns). Arrows = truncation artifacts.
