Hello everyone,

I’m working on a project involving head CT imaging and need to identify and correct artifacts that may interfere with analysis. I’m particularly interested in open-source models or algorithms that can be used within **3D Slicer** or integrated into a similar pipeline without licensing costs.

Specifically, I’m looking for:

- **Artifact detection** (e.g., motion, beam hardening, metal artifacts).
- **Correction methods** that do not require extensive retraining.
- **Plugins or extensions** within Slicer that might be useful.

If anyone has experience with existing models, filters, or workflows that could help with this, I’d appreciate any recommendations!

Thanks in advance!  
JO
