Calculation times CC (old data, so absolute timing obsolete...)

Calculation time is direct proportional to # voxels times # kernel directions:

Example: # voxels=128x128x128 (appr. 2 . 10 6 ), # directions=106

The calculations for the parallel transport lines used in the CC approach are extremely suitable for implementation on parallel hardware!
