Segmenting elements from a CT scan

The XROMM wiki maintained by Brown University has an excellent series of tutorials on creating surface models from CT scans (segmentation) so I will just link to them here.

The following tutorials cover segmenting and creating surface models in either Horos (free, Mac only), 3D Slicer (free), or Amira.

• Creating 3D models using Horos
• Creating 3D models using 3D Slicer
• Creating 3D models using Amira

And the following tutorials cover cleaning surface models in either Meshlab (free) or Geomagic.

• Cleaning models with Meshlab
• Cleaning models with Geomagic
