Summary
TCIA is currently in an alpha testing phase of our REST API implementation. If you are interested in participating in testing the API please contact us at cancerimagingarchive@mail.nih.gov.
REST API URL and Format
This section would benefit from an overview and architecture diagram. The next sections on the API assume you have that understanding. The full API consists of a base URL followed by the api and the query parameters in that order.
For example, in the following URL:
https://services.cancerimagingarchive.net/services/TCIA/TCIA/query/getSeries?collection=TCGA-GBM&patient_id=1.2.3&study_instance_uid=4.5.6
- The base URL is: https://services.cancerimagingarchive.net/services/TCIA/TCIA/query
- The API endpoint is getSeries
- And the three query parameters are provided as follows: collection=TCGA-GBM&patient_id=1.2.3&study_instance_uid=4.5.6
NOTE: The order in which the query parameters are provided does not matter
With the exception of the getImage query, all other queries return a comma separated value (CSV) file with results. The first line of the file contains the names of the columns in the response. Each subsequent line corresponds to one row from the TCIA database. The getImage query returns a zip of the images.

Production / Test URLs and Test Data
There are two RESTful servers provided by TCIA. A test system is loaded with a small set of known data to allow you to test your applications. The production system is configured to use the full TCIA database. The query format is the same for both systems. The base URLs are:
Type | URL |
---|---|
Production | https://services.cancerimagingarchive.net/services/TCIA/TCIA/query |
Test | https://services-test.cancerimagingarchive.net/services/TCIA/TCIA/query |
The test server is loaded with this data:
