Image profiles along the z-axis through the center of Tube-A extracted from images reconstructed by use of (a) the FBP algorithm with fc = 10-MHz from the 720-view data (solid line) the PLS-Q algorithm with α = 1.0 × 103 from the 144-view data (dotted line), and the PLS-TV algorithm with β = 0.05 from the 144-view data (dashed line). Subfigure (b) shows the corresponding profiles for the case where each algorithm employed stronger regularization specified by the parameters fc = 5-MHz, α = 5.0 × 103, and β = 0.1, respectively.
