SSM of Branched Vascular Patient-Specific Geometries _Branch Distortion

Hi,

You may find these references useful:

Creating An SSM for Aortic models

So the main issue here seems to be the scale of the data. For example, I examined one mesh and found the x values ranged from about 0.98 to 1.5. Unfortunately, ShapeWorks has some issues with very small and very large scale data that we are working on resolving. Right now, the best range is 0-100 or so. If these are human aorta in mm range, then they should have already been in a good coordinate space. I scaled your meshes by 100 and played with the parameters a bit. It’s not the best mode…

Advice on SSM of branched vessels?

Hi there, Does anyone have advice on how to best use Shapeworks for vessels? I’ve been trying to create a good SSM of branch pulmonary arteries (and aorta), but so far I have not been successful even with smoothing (using Meshmixer), remeshing and trimming the branches to keep the anatomy as simple as possible. Mean template is still fairly coarse and the shape variations are jagged and non-physiologic. Many thanks in advance. [image]

I would recommend trying the development version of ShapeWorks:

Releases · SCIInstitute/ShapeWorks

In particular, enable “geodesic distance”, “normals”, “procrustes” and “sampling scale”.
