Test on a
semi-sphere, reconstruction from a mathematical model.
The model consists of a hollow semi-sphere with a small full sphere at
Observe that these features are well represented in the 3-D
reconstruction, although with some artifacts.
test is concerned with the evaluation of the spatial long-range
dependencies of density estimates
and the ability to use as few as 4 projective cone-beam views to achieve
meaningful density estimates.
reconstruction was computed on an Intel 860 processor at CTI with a
resolution of about 180-cubed voxels.
The surface renditions 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.
