Paper

CycleMorph: Cycle consistent unsupervised deformable image registration (Medical Image Analysis, Boah Kim et al.) [paper]
Unsupervised Deformable Image Registration Using Cycle-Consistent CNN (MICCAI 2019, Boah Kim et al.)[paper]

Implementation

A PyTorch implementation of deep-learning-based registration. We implemented this code based on voxelMorph and original cycleGAN code. (*Thanks for voxelMorph.) (*Thanks for Jun-Yan Zhu and Taesung Park, and Tongzhou Wang.)

Requirements
- OS : Ubuntu
- Python 3.6
- PyTorch 1.4.0

Data

To download the atlas brain and a sample data, visit the Data. The data should be in folder ./data.

Training

train.py which is handled by scripts/Brain_train.sh
You can run the code by running ./scripts/Brain_train.sh
A code for CycleMorph is in models/cycleMorph_model.py.

Testing

test.py which is handled by scripts/Brain_test.sh
You can run the code by running ./scripts/Brain_test.sh
