What's New

The following APIs were published in April 2022. 

Purpose of this Guide

The National Biomedical Imaging Archive (NBIA) REST APIs allow you to access the search and download functions used in the TCIA radiology portal. 

The NBIA Advanced REST APIs, described on this page, provide capabilities to access restricted collections, which require login authentication. They also provide advanced features that are geared towards developers seeking to integrate searching and downloading TCIA data into their own web and desktop applications.

For information about creating basic queries and downloading data for image analysis, refer to the NBIA Search REST API Guide and NBIA Search with Authentication REST API Guide.

NBIA Advanced REST API Base URL, Format, and Return Values

Access to any NBIA Advanced REST API requires an authentication token. You must contact the TCIA Help Desk to receive the client_id and client_secret needed to generate a token. If you want to access restricted collections, the TCIA Help Desk must give your user account permission to access them. 

The full API for data consists of a base URL followed by the API and query parameters, in that order. The base URL to access NBIA Advanced REST API data is https://services.cancerimagingarchive.net/nbia-api/services. 

URLs to Access NLST Data

To access National Lung Screening Trial (NLST) data, get the authentication token from https://nlst.cancerimagingarchive.net/nbia-api/oauth/token, then use https://nlst.cancerimagingarchive.net/nbia-api/services/ to make REST API calls.

NBIA Advanced REST API Query Structure

<Token><BaseURL><Resource><QueryEndpoint>?<QueryParameters>

For example, the API shown below requests all Body Part Values and Counts for the PT modality.

Example NBIA Advanced REST API Query

curl -H "Authorization:Bearer cd2b2895-85d0-49c5-bd75-804f162da942" -k "https://services.cancerimagingarchive.net/nbia-api/services/getBodyPartValuesAndCounts?Modality=PT"

We can break this down as follows.

ObjectExample

BaseURL

https://services.cancerimagingarchive.net

Resource/nbia-api/services
EndpointgetBodyPartValuesAndCounts
Query ParametersModality=PT

If the value for an attribute is not populated in the specified collection, it will not appear in the returned values.

All APIs return results in JSON format except for the Thumbnail API (JPG), Manifest Text API (TXT), and Series Metadata API (CSV).

Secure Access to NBIA REST Services

Access to any NBIA Advanced REST API requires a token that you must request.

The credentials you pass differ based on whether the collections include public or restricted data. You must contact the TCIA Help Desk for permission to access private collections and receive the client_id and client_secret values required for RESTful access to those collections. 

The NBIA REST API supports secure access to private data in the Client Credentials authorization flow with Spring Security and OAuth2. The Client Credentials authorization flow is also known as "signed fetch" or 2-legged OAuth. The following figure illustrates the typical use case for REST API calls made on the web using 2-legged OAuth. For more information regarding the specific workflow, consult the OAuth2 Specification. 


     +---------+                                  +---------------+

     |         |>--(A)- Client Authentication --->| Authorization |
     | Client  |                                  |     Server    |

     +---------+                                  +---------------+

Figure 1: Client Credentials Flow

This flow includes the following steps:

  1. The client authenticates with the authorization server and requests an access token from the token endpoint.
  2. The authorization server authenticates the client, and if valid, issues an access token.

This token can then be used on subsequent requests to authorize access to resources. The NBIA Advanced REST API server also supports token expiration and extension by refresh. The time it takes tokens to expire is currently two hours but is configurable.

To access TCIA using an NBIA Advanced REST API, you must do the following:

Requesting a Token

Access to any NBIA Advanced REST API requires an authentication token. You must contact the TCIA Help Desk to receive the client_id and client_secret needed to generate a token. 

A request for a token takes the following structure. Refer to the table below for the correct username and password to pass in the call.

Structure of a Request for a Token
curl -d "username=<username>&password=<password>&client_id=<theClientIDFromHelpDesk>&client_secret=<theClientSecretFromHelpDesk>&grant_type=password" -X POST -k https://services.cancerimagingarchive.net/nbia-api/oauth/token


DataUsernamePassword
Public and RestrictedYour usernameYour password
Publicnbia_guestLeave blank

Request a token by interacting with the application in the following way.

  1. The application requests credentials. The credentials you pass are different depending on if you want to access public or restricted data (see above).

  2. The application sends a request to the service using the credentials you provided as a query string for the body. 

    • grant_type=password
    • username
    • password

  3. The service responds with access token details and expiration information.

    • access_token
    • expires_in
    • token_type

    The application makes a request for resources using the returned access token. All APIs listed for accessing public data also support secure access to restricted data with an additional parameter for the access token. 

How a Token is Returned/Granted/Given

A successful token request returns a standard access token in JSON format.

Sample Token Return Value
{"access_token":"f7889076-b3e4-4768-9419-3cd973adda76","token_type":"bearer","refresh_token":"671bb72b-f929-4ef5-a4d7-b52341a6007a","expires_in":7199}

Using the Token in an API Call

Make a note of the access token you received and pass it with the REST service call.

Sample NBIA Advanced REST API Call
# Request for modality values and counts           
curl -H "Authorization:Bearer c428d42c-9eed-4f5d-8007-416d46be9b52" -k "https://services.cancerimagingarchive.net/nbia-api/services/getModalityValuesAndCounts?Collection=LIDC-IDRI"

A successful service request returns the value in a defined format. 

Request for Refreshing the Token

The time it takes tokens to expire is configurable but is currently two hours.

Sample Request for Refreshing the Token
# Request for refreshing the token  

$ curl -X -v -d "refresh_token=7c2414a1-1f2f-4c9e-82a0-69fcb9fd18ed&client_id=nbiaRestAPIClient&client_secret=ItsBetweenUAndMe&grant_type=refresh_token" -X POST -k https://services.cancerimagingarchive.net/nbia-api/oauth/token
        
/nbia-api/oauth/token"

In the following result, 119 is the seconds before the token expires.

Sample Return Value
{"access_token":"bbe4aa2c-7235-41ad-9770-31619d3dbd15","token_type":"bearer","refresh_token":"671bb72b-f929-4ef5-a4d7-b52341a6007a","expires_in":119}

Example Request to Logout

Sample Request to Logout
# Request for logout   
      
$ curl -H "Authorization:Bearer caa278aa-e7a9-45b8-a7ec-2c83d4b03cc0" -k "https://services.cancerimagingarchive.net/nbia-api/logout"

Result

Sample Return Value
