Figure 5:

Performance of all the schemes as a function of slice position: The figure shows comparison between view-sharing, nuclear norm minimization scheme, l₁ Fourier sparsity regularization scheme and BCS scheme (Rows 1–4) for slices positioned at the center (1^st column), anterior (2^nd column), and posterior (3^rd column) of the lung. We observe that all schemes except the BCS scheme suffer from higher temporal blurring in the slices at anterior and posterior regions of the lung than those in the center region. BCS scheme is relatively insensitive to the slice position as compared to other schemes.
