Original Numerical Phantom
with "Coronary Arteries"
3-D Reconstruction from Six Projections after Removal of "Coronary Arteries"
Cut-Away View
Model of the myocardium (with "coronaries", left) and cut-away view of the 3-D reconstruction after removal of the coronary arteries (right).
Coronary+Myocardium Model
CutMyocardium, NumericalReconstruction
Model of epi-endocardial  blushgradient in the myocardium (factor of two of blush-density; with "coronaries"; left) and cut-away view of 3-D reconstruction (right) EpiEndicardialGradient, Numerical
CutEpiEndocardialGradient, Reconstruction
Model of region-at-risk in the myocardium (factor of two of reduced blush-density; with "coronaries"; left) and cut-away view of 3-D reconstruction (right)

The visualization threshold on the left was set above that of the density of the "region-at-risk" and is seen as indentation.

The visualization threshold on the right was set below the density of the "region-at-risk" and is seen as pale / non-blushed area in the front of the section (the perfusion density is indicated by the blush intensity).
