Vision Transformer for 3D medical image registration (Pytorch).

ViT-V-Net: Vision Transformer for Volumetric Medical Image Registration

Please also check out our newly proposed registration model 👉 TransMorph
The pretrained model and the quantitative results of ViT-V-Net on IXI dataset are available here: IXI_dataset.
Additionally, we have made our preprocessed IXI dataset publicly available!

This is a PyTorch implementation of my short paper:

Chen, Junyu, et al. "ViT-V-Net: Vision Transformer for Unsupervised Volumetric Medical Image Registration. " arXiv, 2021.

train.py is the training script. models.py contains ViT-V-Net model.

Dataset: Due to restrictions, we cannot distribute our brain MRI data. However, several brain MRI datasets are publicly available online: IXI, ADNI, OASIS, ABIDE, etc. Note that those datasets may not contain labels (segmentation). To generate labels, you can use FreeSurfer, which is an open-source software for normalizing brain MRI images. Here are some useful commands in FreeSurfer: Brain MRI preprocessing and subcortical segmentation using FreeSurfer.
