Fig. 3From: Assessment of local pulse wave velocity distribution in mice using k-t BLAST PC-CMR with semi-automatic area segmentationSemi-automatic segmentation of the cross sectional area of the vessel lumen. For a given threshold the time course of the cross sectional area was automatically determined for each of the three flow encoding steps. The threshold delivering the minimal deviation between the three segmentation results was considered as the optimum resultBack to article page
