Hi, I want to correct the iMRI geometry distortion. I have no idea which extensions can correct such issue. May I know if 3D slicer can do this?

Thanks,

Happy New Year

Many groups have developed MRI distortion correction using 3D Slicer, but I’m not sure if they made their source code available - a few examples:

- [Phantom study to correct geometric distortion in MRI imaging (Moving image) based on CT imaging (Fixed image)](https://discourse.slicer.org/t/phantom-study-to-correct-geometric-distortion-in-mri-imaging-moving-image-based-on-ct-imaging-fixed-image/4383/4)
- [http://www.cirsinc.com/wp-content/uploads/2018/12/COMP-Poster-2018-Chelsea-v5.pdf](http://www.cirsinc.com/wp-content/uploads/2018/12/COMP-Poster-2018-Chelsea-v5.pdf)
- [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5539340/](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5539340/) (and [thesis](https://digitalcommons.wayne.edu/cgi/viewcontent.cgi?httpsredir=1&article=2575&context=oa_dissertations))

You can contact the authors to see if they are willing to share their software. Keep us updated about what you ended up achieving (or let us know if you need more help).

Thanks Andras for your information, I will let you know if I have any progress in this.

Thanks Again.
