Hello, I have an input DWI dataset and wanna perform the EPI correction (magnetic susceptibility induced distortion, geometric distortion…). Does 3D Slicer enable to perform the EPI correction?

Thanks a lot  
Regards  
Adam

If you have your corrective transform as an ITK transform (grid, b-spline, thin-plate-spline or a composite of these) or as a 3D vector volume (containing dense displacement field) then you can apply that to any node, such as volumes, models, point sets, etc. using Transforms module.

Thanks a lot. Please, where to obtain the corrective transform matrix on my input DWI data set. Does 3D Slicer enable to get it? Or any other program?
