Dear Bernard, you can find the details in my IEEE TMI paper from 2004: Antiga L and Steinman DA. Robust and objective decomposition and mapping of bifurcating vessels. IEEE Transactions on Medical Imaging, 23(6): 704-713, June 2004.
and also here http://www.vmtk.org/Tutorials/BranchSplitting/ In short, ICA (ECA) reference points are located where the ICA (ECA) cross the tube surface of the ECA (ICA). The CCA reference points are located one inscribed sphere radius away from each ICA and ECA points in the upstream direction. Hope this helps Luca On Jun 6, 2012, at 3:42 PM, Bernard Chiu wrote: > Dear vmtk users > > In the output of the vmtkBifurcationVectors filter, there are three > points, one for each of the CCA, ICA and ECA.
