Step 2: Set one or more seed points.
There are two different types of seed points:
Center points – e.g. one click for the complete aorta
End points – e.g. prevents the segmentation to run
from carotids into aortic arch.
You can set points in all segments.
You may set any number of center points and/or end
points. For the segmentation of coronaries, two end
points have to be set.
Step 3: Adjust sensitivity (threshold for segmentation).
Set the required threshold value with the slider.
Voxels of an intensity below the segmentation thresh-
old are excluded from the image segment. Check the
view and correct the setting if necessary.
Step 4: Define paths along the branches of the vessel
tree by performing two clicks into the VRT
image for each path. You may define as many
paths as necessary.
As soon as you have created all paths click Done.
Paths are displayed in the image segments as a colored
line through the middle of the vessel.
