Figure 5.

(a) Split central slice image, reconstructed from synthetic projections computed without BTF with veiling glare (right half) and without (left half); (b) Profiles through images reconstructed from projections with and without veiling glare PSF convolution. No correction for scatter or beam hardening was made in the polyenergetic case while the monoenergetic simulation assumed perfect scatter compensation, (c) Split image, (veiling glare on right side, no veiling glare on left side), for polyenergetic projections with BTF; and (d) Same as (b) except for projection data assuming BTF.
