We strongly believe in open and reproducible deep learning research. Our goal is to implement an open-source medical image segmentation library of state of the art 3D deep neural networks in PyTorch. We also implemented a bunch of data loaders of the most common medical image datasets. This project started as an MSc Thesis and is currently under further development. Although this work was initially focused on 3D multi-modal brain MRI segmentation we are slowly adding more architectures and data-loaders.
[Update] 21-07 We have just received a brand new GPU. The project developedment was postponed due to lack of computational resources. We will be back with more updates. Please Watch our Github repository for releases to be notified. We are always looking for passionate open-source contributos. Full credits will be given.

If you want to quickly understand the fundamental concepts for deep learning in medical imaging, we strongly advice to check our blog post. We provide a general high-level overview of all the aspects of medical image segmentation and deep learning. For a broader overview on MRI applications find my latest review article.

For a more holistic approach on Deep Learning in MRI you may advice my thesis this.

Alternatively, you can create a virtual environment and install the requirements. Check the installation folder for more instructions.
-
You can also take a quick glance at the manual.

If you do not have a capable environment or device to run this projects then you could give Google Colab a try. It allows you to run the project using a GPU device, free of charge. You may try our Colab demo using this notebook:

In general, in the open source community recognizing third party utilities increases the credibility of your software. In deep learning, academics tend to skip acknowledging third party repos for some reason. In essence, we used whatever resource we needed to make this project self-complete, that was nicely written. However, modifications were performed to match the project structure and requirements. Here is the list of the top-based works: HyperDenseNet model. Most of the segmentation losses from here. 3D-SkipDenseNet model from here. 3D-ResNet base model from here. Abstract model class from MimiCry project. Trainer and Writer class from PyTorch template. Covid-19 implementation based on our previous work from here. MICCAI 2019 Gleason challenge data-loaders based on our previous work from here. Basic 2D Unet implementation from here.Vnet model from here
