This the official repository for uniGradICON
: A Foundation Model for Medical Image Registration
uniGradICON
is based on GradICON but trained on several different datasets (see details below).
The result is a deep-learning-based registration model that works well across datasets. More results can be found here.

Our goal is to continuously improve the uniGradICON
model, e.g., by training on more datasets with additional diversity. Feel free to point us to datasets that should be included or let us know if you want to help with future developments.
To use:
python3 -m venv unigradicon_virtualenv
source unigradicon_virtualenv/bin/activate
pip install unigradicon
wget https://www.hgreer.com/assets/slicer_mirror/RegLib_C01_1.nrrd
wget https://www.hgreer.com/assets/slicer_mirror/RegLib_C01_2.nrrd
unigradicon-register --fixed=RegLib_C01_2.nrrd --fixed_modality=mri --moving=RegLib_C01_1.nrrd --moving_modality=mri --transform_out=trans.hdf5 --warped_moving_out=warped_C01_1.nrrd
To register without instance optimization (IO)
unigradicon-register --fixed=RegLib_C01_2.nrrd --fixed_modality=mri --moving=RegLib_C01_1.nrrd --moving_modality=mri --transform_out=trans.hdf5 --warped_moving_out=warped_C01_1.nrrd --io_iterations None
To use a different similarity measure in the IO. We currently support three similarity measures
- LNCC: lncc
- Squared LNCC: lncc2
- MIND SSC: mind
unigradicon-register --fixed=RegLib_C01_2.nrrd --fixed_modality=mri --moving=RegLib_C01_1.nrrd --moving_modality=mri --transform_out=trans.hdf5 --warped_moving_out=warped_C01_1.nrrd --io_iterations 50 --io_sim lncc2
To load specific model weight in the inference. We currently support uniGradICON and multiGradICON.
unigradicon-register --fixed=RegLib_C01_2.nrrd --fixed_modality=mri --moving=RegLib_C01_1.nrrd --moving_modality=mri --transform_out=trans.hdf5 --warped_moving_out=warped_C01_1.nrrd --model multigradicon
To warp an image
unigradicon-warp --fixed [fixed_image_file_name] --moving [moving_image_file_name] --transform trans.hdf5 --warped_moving_out warped.nii.gz --linear
To warp a label map
unigradicon-warp --fixed [fixed_image_file_name] --moving [moving_image_segmentation_file_name] --transform trans.hdf5 --warped_moving_out warped_seg.nii.gz --nearest_neighbor
We also provide a colab demo.
UniGradICON
is set up to work with Itk images and transforms. So you can easily read and write images and display resulting transformations for example in 3D Slicer.
