This page describes the representational state transfer application programming interface (REST API) implementations that can be used to access TCIA data and resources. The APIs complement the existing web interfaces and enable developers to build direct access to TCIA data into their applications using only the API documentation provided. The application developer must ensure that they and the users of their applications comply with the TCIA Data Usage Policy. If you are interested in using the APIs and have any questions, please contact the TCIA Help Desk except where otherwise noted.

• NBIA REST APIs: Provided as part of the NBIA software, these APIs provide access to the search and download functions used in the TCIA radiology portal, and allow access to both public and limited access DICOM collections.
  • The NBIA Search REST APIs allow you to perform basic queries and download data for image analysis on public collections.
  • The NBIA Search with Authentication REST APIs allow you to perform basic queries on and download data for image analysis from public and restricted collections.
  • The NBIA Advanced REST APIs also allow access to public and restricted collections, but are geared towards developers seeking to integrate searching and downloading TCIA data into their own web and desktop applications. 
• DataCite REST API: Each Collection TCIA publishes is issued a Digital Object Identifier (DOI) through DataCite.  This API can be used to programmatically access Collection metadata such as their DOIs, titles and abstracts.  Please note that this API was not developed by TCIA. See https://support.datacite.org/ for any technical questions.  The TCIA Helpdesk may be able to assist if your inquiry is related to the content of the data itself.
• TCIA REST API: [DEPRECATED 6-22-2022] - The TCIA REST API originally developed using Project Bindaas with Emory University, has been deprecated in favor of the NBIA REST APIs. While the NBIA REST APIs have the same functionality as the Bindaas based TCIA REST APIs, there are some differences that should be noted and tested during conversion from the TCIA REST API to the NBIA REST API. Please see the Migration Guide for details. The existing Bindaas based TCIA REST APIs will remain active but will receive no updates or maintenance going forward.  They also do not contain an up-to-date view of our available datasets, so newer collections will not appear if you use them.

TCIA_Utils

The tcia_utils package contains functions to simplify common tasks one might perform when interacting with The Cancer Imaging Archive (TCIA) via Python.  Issues with this package should be submitted at https://github.com/kirbyju/tcia_utils/issues.  Example notebooks demonstrating tcia_utils functionality can be found at https://github.com/kirbyju/TCIA_Notebooks. 

Installation can be achieved with this Pip command:

pip install tcia_utils

 To import functions related to NBIA for accessing our DICOM radiology data:

from tcia_utils import nbia

To import functions related to pathDB for accessing our digitized pathology data:

from tcia_utils import pathdb

To import functions related to Datacite for querying Collection metadata such as their DOIs, titles and abstracts:

from tcia_utils import datacite
