Hello:

Iam a new comer to Slice. I would like to create a mesh of vessel (from MRI data) and would like to save as .obj file for export in to modeling software. Can someone help me how I can go about creating mesh and save as .obj?

Thank you in advance!

You can also use VMTK extension’s `Vesselness filtering` module for enhancing vessel visibility on the images. You may be able to extract vessels by simple thresholding of the vesselness image (followed by speckle removal using Islands effect / Keep largest island options; and Smoothing effect).

Once you are done with segmentation, you can export the segment to a Model node (using Segmentations module), which can be saved as an .obj file.

Hi Andres:

Thank you so very much. Is there a tutorial that walks me through VMTK routine?

Thanks

There’s this tutorial. It’s quite old and it shows an overly simple case, but it shows you how it’s done
