Data Usage Policy
Any user accessing TCIA data must agree to:
- Not use the requested datasets, either alone or in concert with any other information, to identify or contact individual participants from whom data and/or samples were collected and follow all other conditions specified in our Site Disclaimer. Approved Users also agree not to generate and use information (e.g., facial images or comparable representations) in a manner that could allow the identities of research participants to be readily ascertained. These provisions do not apply to research investigators operating with specific IRB approval, pursuant to 45 CFR 46, to contact individuals within datasets or to obtain and use identifying information under an IRB-approved research protocol. All investigators including any Approved User conducting “human subjects research” within the scope of 45 CFR 46 must comply with the requirements contained therein.
- Acknowledge in all oral or written presentations, disclosures, or publications the specific dataset(s) or applicable accession number(s) and the NIH-designated data repositories through which the investigator accessed any data. Citation guidelines for doing this are outlined below.
- If you are considering mirroring a copy of our publicly available datasets or providing direct access to any of our data via another tool or website using our REST API please review our Data Analysis Centers (DACs) page for more information. DACs must provide attribution and links back to this TCIA data usage policy and require downstream users to do the same.
The summary page for every TCIA dataset includes a Citations & Data Usage Policy tab (see screenshot below). Please consult the Citation & Data Usage Policy for each Collection before using them.
- Most data are freely available to browse, download, and use for commercial, scientific and educational purposes as outlined in the Creative Commons Attribution 3.0 Unported License or the Creative Commons Attribution 4.0 International License. A small number of collections impose Creative Commons licenses with commercial use restrictions, but this is no longer an option for new submissions.
- Most data are immediately accessible and do not require account registration. A small subset of collections do require registration and special permission to gain access. Refer to the "Access" column on https://www.cancerimagingarchive.net/collections/ for more details. Limited Access Collections are currently released under 1 of 2 custom license options:
TCIA takes every step possible to protect the privacy of participants that have agreed to share their data to promote cancer research. Therefore, effective January 6, 2022, all TCIA Collections of brain, head or head/neck cancers (where data could be used to reconstruct a human face) will change from a Creative Commons license to a TCIA Limited Access License. The data will still be available to download for research, but you will need a TCIA account and an approved License Agreement on file with the TCIA Help Desk.
Citing TCIA (general)
For any manuscript developed using data from The Cancer Imaging Archive please cite the relevant collection(s) you've used (see below) as well as the following TCIA publication:
Clark K, Vendt B, Smith K, Freymann J, Kirby J, Koppel P, Moore S, Phillips S, Maffitt D, Pringle M, Tarbox L, Prior F. The Cancer Imaging Archive (TCIA): maintaining and operating a public information repository. Journal of Digital Imaging. 2013 Dec;26(6):1045-57. DOI: 10.1007/s10278-013-9622-7
If you have utilized TCIA in your research, please contact us at email@example.com so we can include your work on our Related Publications page. We also encourage researchers to tweet about their TCIA-related research with the hash tag #TCIAresearch.
Citing Specific TCIA Collections
Each published TCIA Collection has an associated data citation. When citing a TCIA collection, be sure to use the full data citation rather than citing the wiki page as a URL. Researchers can use https://citation.crosscite.org/ to create citations in the accepted format for most major publishers if you paste in the Digital Object Identifier (DOI) from a TCIA dataset. Consult the Citation & Data Usage Policy found on each Collection's summary page (see screenshot above) to learn more about how it should be cited and any usage restrictions. For some collections, there may also be additional papers that should be cited listed in this section.
