Clinical 4D dynamic contrast enhanced MR images with focus on the liver.
Motion correction for contrast enhanced time series of the abdomen.
For parameter files see the Elastix Model Zoo repository on GitHub.
elastix version: 4.801
For Groupwise Registration PCAmetric2 was used.
For groupwise registration one should use the following command line call:
elastix -f <4D DCE-MRI image> -m <4D DCE-MRI image> -p -out
where <4D DCE-MRI image> is the entire group of images that are acquired in a single DCE-MRI acquisition. Note that the fixed and moving image should be the same. The fixed image is not used for the registration, but acts as a dummy to prevent elastix throwing error messages.
