mri-distortion-toolkit 0.12.0

Quality assurance tools for MRI geometric distortion

mri_distortion_toolkit

This code enables characterization, reporting, and correction of geometric distortion in Magnetic Resonance Imaging.

For the measurement of such distortions, see here.

The workflow steps are below, but all steps have well defined input/output so you can use any part of this code independently from the other parts. For a tutorial on each step, click on the diagram below. For an example of our automated reporting template see here
