you give information about the Colliding level set filter. I mean any

<br>
In order to use this filter you need to pass two seed points,<br>
one at each end of the vessel that you want to extract.<br>
<br>
You could put one seed point in the aneurysm and the other<br>
in one section of the vessel in which the aneurysm is located.<br>
<br>
You will find a source code example on how to use this<br>
class in the file:<br>

<br>
The outcome of the filter will be the sequence of<br>
pixels that trace a line between the two seed points,<br>
and follows the intensities of the image.<br>
<br>
<br>
If you also need to segment the inflated portion of<br>
the aneurysm, then you could follow up this with a<br>
standard FastMarchingImageFilter segmentation.<br>
<br>
This filter is described in the ITK Software Guide<br>
<br>
<a href="http://www.itk.org/ItkSoftwareGuide.pdf" target="_blank">http://www.itk.org/ItkSoftwareGuide.pdf</a><br>
<br>
and you will find examples in<br>
<br>
Insight/Examples/Segmentation<br>
<br>
as well as interactive applications in<br>
<br>
InsightApplications/FastMarchingLevelSet<br>
