Kanavati, F., Islam, S., Arain, Z., Aboagye, E. O., & Rockall, A. (2020). Fully-automated deep learning slice-based muscle estimation from CT images for sarcopenia assessment. arXiv preprint arXiv:2006.06432.
Trained models for slice detection and slice segmentation are provided in models/
conda create -y --name sarcopenia-ai python=3.6.2
Install
pip install -e .
docker build -t sarcopeniaai -f ./Dockerfile .
Download the training data from here to your data folder.
docker run --rm -it -v <your_data_folder>:/data -v $(pwd)/configs:/configs sarcopeniaai python -m sarcopenia_ai.apps.slice_detection.trainer --config /configs/slice_detection.cfg
Training output preview on validation images
Labelled segmentation data is not provided. Once you get your own data, you can train a segmentation model with
docker run --rm -it -v <your_data_folder>:/data -v $(pwd)/configs:/configs sarcopeniaai python -m sarcopenia_ai.apps.segmentation.trainer --config /configs/segmentation.cfg
docker run --rm -it -p 5000:5000 sarcopeniaai python -m sarcopenia_ai.apps.server.run_local_server
Then head to http://localhost:5000 for web UI
You can also get results from command line. Example:
curl -X POST -F image=@data/volume.nii.gz http://localhost:5000/predict

The dataset was collected from multiple sources:
3 sets were obtained from the Cancer Imaging Archive (TCIA):
a liver tumour dataset was obtained from the LiTS segmentation challenge.
The dataset is available for download in MIPs format from here.
The subset of transitional vertabrae cases can be downloaded from here.
