Figure 5. — (a) The reconstructed images. From the top row to the bottom: DEAM-NW: baseline (reconstruction from undistorted sinograms), iFBP: initial condition (image-based decomposition with image warping), DEAM-Linear: warped DEAM with linear interpolation (Jacobian-weighted inverse), DEAM-Bspline: warped DEAM with B-Spline interpolation (Jacobian-weighted inverse), and DEAM-adjoint: warped DEAM with linear interpolation (adjoint). From left column to the right: c ₁ with display window [–0.2, 1.2], c ₂ with display window [–0.2, 1.2], virtual mono-energetic image (VMI) at 20, 60, and 140 keV estimated from c ₁ and c2_. (b) and (c): zoomed-in version of the reconstructed images. (d) Shows the profiles of the different DEAM algorithms through five regions of interest (ROI) shown in the lower-left image of (a).
