🤩 About the Project

Warning: This project is currently in alpha stage and may be subject to major changes

This repository presents a suite of unified scripts to standardize, preprocess, and integrate 882,774 images from 20 open-source medical imaging datasets, spanning modalities such as X-ray, CT, and MR. The scripts allow for seamless and fast download of a diverse medical data set. We create a unified set of annotations allowing for merging the datasets together without mislabelling. Each dataset is preprocessed with a custom sklearn pipeline. The pipeline steps are reusable across the datasets. The code was designed so that preorocessing a new dataset is simple and requires only reusing the available pipeline steps with customization performed through setting the appropriate values of the pipeline params.

The labels and segmentation masks were unified to be compliant with RadLex ontology.

Creating the dataset

Due to the copyright restrictions of the source datasets, we can't share the files directly. To obtain the full dataset you have to download the source datasets yourself and run the preprocessing scripts.

To preprocess the dataset that is not among the above, search the preprocessing folder. It contains the reusable steps for changing imaging formats, extracting masks, creating file trees, etc. Go to the config file to check which masks and label encodings are available. Append new labels and mask encodings if needed.
