Introductory lessons to deep learning for medical imaging by MD.ai
The following are several Jupyter notebooks covering the basics of training deep learning models for medical imaging using data from MD.ai. They demonstrate how to download and parse annotation data from MD.ai, as well as train and evaluate different deep learning models for classification, segmentation, and object detection problems. The notebooks can be run on Google Colab with GPU (see instruction below).
| # | Name | GitHub | MD.ai | Colab |
|---|---|---|---|---|
| 1 | Classification of chest vs. adominal X-rays using TensorFlow/Keras | Link | Link |  |
| 2 | Lung X-Rays Semantic Segmentation using U-Nets | Link | Link | |
| 3a | RSNA Pneumonia detection using Kaggle data format | Link | Link | |
| 3b | RSNA Pneumonia detection using the MD.ai python client library | Link | Link | |
Note that the mdai client requires an access token, which authenticates you as the user. To create a new token or select an existing token, to go a specific MD.ai domain (e.g., public.md.ai), register, then navigate to the "Personal Access Tokens" tab on your user settings page to create and obtain your access token.
MD.ai Annotator
MD.ai annotator is a web-based application to store, view, and collaboratively annotate medical images (e.g, DICOM) in the cloud. The MD.ai python client library can be used to download images and annotations, prepare the datasets, and then be used to train and evaluate deep learning models. Further documentation and videos are available at https://docs.md.ai/.

Running Jupyter notebooks on Google Colab
It’s easy to run a Jupyter notebook on Google Colab with free GPU use within time-limited sessions. For example, add the Github Jupyter notebook path to https://colab.research.google.com/notebook:
Select the "GITHUB" tab, and add the Lesson 1 URL: https://github.com/mdai/ml-lessons/blob/master/lesson1-xray-images-classification.ipynb
To use the GPU, in the notebook menu, go to Runtime -> Change runtime type -> switch to Python 3, and turn on GPU. See more Colab tips and tricks here.
