The National Cancer Institute Imaging Data Commons (IDC) is a cloud-based repository of publicly available cancer imaging data, co-located with analysis and exploration tools. As part of the NCI Cancer Research Data Commons (CRDC), IDC provides researchers with:
- Access to >85 TB of cancer imaging data, including radiology, brightfield, and fluorescence microscopy images
- Image-derived data such as annotations, segmentations, and quantitative measurements
- Accompanying clinical data
- Cloud-based infrastructure for data exploration and analysis
- Free and open access: No registration or access requests required
- Commercial-friendly licensing: >95% of data covered by CC-BY license
- Cloud-based: Data available from both Google and AWS public buckets
- Standardized data: All images and derived data harmonized into DICOM format
Our GitHub organization hosts various repositories to support IDC users:
- IDC-Tutorials: Self-guided notebook tutorials to help you get started with IDC

We are also maintianing a number of repositories containing popular tools that we use in IDC, but which are of general utility:
- highdicom: high-level DICOM abstractions for the Python programming language
- Slim: interoperable web-based DICOM slide microscopy viewer and annotation tool
- dicom-microscopy-viewer: Web-based DICOM slide microscopy viewer library
- dicomweb-client: python client for DICOMweb RESTful services
- libdicom: C library for reading DICOM files
- s5cmd-python-distributions: package that allows you to install
s5cmd
command line tools withpip
