Hi there ImageVis users

I currently use Slicer and VMTK.

- At the moment have a project segmenting large numbers of abdominal aortic
aneurysms
- this is performed on CT angio data
- it's important that I accurately segment any main branches from the aorta,
and the early/proximal branches of these main branches

Currently I perform some volume rendering in Slicer, and threshold out a model
to get a rough idea of the vessels that're present prior to performing the
segmentation in VMTK. However more often than not neither of these methods
show the small branches or early branches, so I'm left going through the CT
slice-by-slice, carefully looking for vessels this way.

I was hoping that ImagVis may have improved volume rendering capabilities for
this sort of work. Is anyone able to advise if this is likely to be the case,
and offer some tips for this?

Hope to hear,
T
