Hi,
I would like to automatically extract the brain from CT angiograms using a Python script. I have tested the WrapSolidify extension in 3D Slicer, and it works well (see screenshot). My questions are :
1 - How can I implement such a method directly in Python, without using a GUI?
2 - If WrapSolidify is not possible to use in such a way, what are the best approaches for brain extraction from CT angiograms (without relying on deep learning models)?
Thank you in advance for your help!

Hello @malar563,
Possibly mimic the workflow of the [SlicerSwissSkullStripper](https://github.com/lassoan/SlicerSwissSkullStripper) which doesn’t rely on Deep Learning (DL).
If you lift this restriction, possibly try [TotalSegmentator](https://github.com/wasserth/TotalSegmentator) which is DL, but you only need to do inference so no requirements for large dataset for training.

You might be able to run that WrapSolidify extension in a python script using Slicer’s docker container.
Here’s the SlicerDockers repo if you want to try that approach:

@lassoan might want to comment too.
