cone-beam projections of a bovine coronary cast (silicon with Thorium).
The projection data were provided by J. Richard Spears, MD.
test is concerned with evaluating the ability to reconstruct a complex
coronary tree with as few as 4 projective views.
on these results it appears that either more views or additional
constraints on the nature of vessels (continuity) are needed to
reduce the effect of phantom artifacts.
The reconstruction was computed on an Intel 860 processor at CTI with
a resolution of about 180-cubed voxels.
The surface renditions below were computed on a SUN station. Note: black
surface patches are due to defects in the
rendition algorithm provided on that system and are not a result
of the 3-D reconstruction.
