DDMR: Deep Deformation Map Registration

Learning deep abdominal CT registration through adaptive loss weighting and synthetic data generation

DDMR was developed by SINTEF Health Research. The corresponding manuscript describing the framework has been published in PLOS ONE and the manuscript is openly available here.

💻 Getting started

1. Setup virtual environment:

virtualenv -ppython3 venv --clear
source venv/bin/activate

2. Install requirements:

pip install git+https://github.com/jpdefrutos/DDMR

🤖 How to use

Use the following CLI command to register images

ddmr --fixed path/to/fixed_image.nii.gz --moving path/to/moving_image.nii.gz --outputdir path/to/output/dir -a <anatomy> --model <model> --gpu <gpu-number> --original-resolution

where:

• anatomy: is the type of anatomy you want to register: B (brain) or L (liver)
• model: is the model you want to use:
  • BL-N (baseline with NCC)
  • BL-NS (baseline with NCC and SSIM)
  • SG-ND (segmentation guided with NCC and DSC)
  • SG-NSD (segmentation guided with NCC, SSIM, and DSC)
  • UW-NSD (uncertainty weighted with NCC, SSIM, and DSC)
  • UW-NSDH (uncertainty weighted with NCC, SSIM, DSC, and HD).
• gpu: is the GPU number you want to the model to run on, if you have multiple and want to use only one GPU
• original-resolution: (flag) whether to upsample the registered image to the fixed image resolution (disabled if the flag is not present)

Use ddmr --help to see additional options like using precomputed segmentations to crop the images to the desired ROI, or debugging.

🤗 Demo

A live demo to easily test the best performing pretrained models was developed in Gradio and is deployed on Hugging Face.

To access the live demo, click on the Hugging Face badge above. Below is a snapshot of the current state of the demo app.

Development

To develop the Gradio app locally, you can use either Python or Docker.

Python

You can run the app locally by:

python demo/app.py --cwd ./ --share 0

Then open http://127.0.0.1:7860 in your favourite internet browser to view the demo.

Docker

Alternatively, you can use docker:

docker build -t ddmr .
docker run -it -p 7860:7860 ddmr

Then open http://127.0.0.1:7860 in your favourite internet browser to view the demo.

🏋️‍♂️ Training

Use the "MultiTrain" scripts to launch the trainings, providing the neccesary parameters. Those in the COMET folder accepts a .ini configuration file (see COMET/train_config_files/ for example configurations).

For instance:

python TrainingScripts/Train_3d.py

🔍 Evaluate

Use Evaluate_network to test the trained models. On the Brain folder, use Evaluate_network__test_fixed.py instead.

For instance:

python EvaluationScripts/evaluation.py
