What's New

The following APIs were published in February 2021:

Purpose of this Guide

This guide documents the NBIA REST Search APIs released since NBIA at TCIA version 7.5 in April 2020. 

The National Biomedical Imaging Archive (NBIA) software is the radiology portal for DICOM images at The Cancer Imaging Archive. This document describes the NBIA’s representational state transfer application programming interfaces (REST API). The APIs are designed for use by image analysis and data mining tools to directly query the public and private resources of the TCIA Radiology Portal and retrieve information into their applications. The API complements the existing web interface but eliminates the need for users to visit the TCIA web pages to select and download images and then upload them into their viewing and analysis applications.

The API is a RESTful interface, accessed through web URLs. There is no software that an application needs to download to use the APIs. The application can build its own access routines using only the API documentation provided here. The interface employs predefined query functions (see REST Search APIs) that access databases.

NBIA Search API Base URL, Format, and Return Values

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 Search data is https://services.cancerimagingarchive.net/nbia-api/services.

Access to any NBIA Search 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. 

You access a resource by sending an HTTPS request to the NBIA Search API server. The server replies with a response that either contains the data you requested or a status indicator. 

An NBIA Search API query takes the following structure:

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

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

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.

BaseURL

https://services.cancerimagingarchive.net

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

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

Secure Access to NBIA REST Services

Access to any NBIA Search 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

Client Credentials Flow

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 Search REST 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 Search REST API, you must do the following:

Requesting a Token

Access to any NBIA Search 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.

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. 

Example Request for a Token to Access Public Collections

All public collections are accessible through the nbia_guest account without a password. Do the following to request a token to use when accessing public data.

# Request for token to access public data
          
$ curl -X -v -d "username=nbia_guest&password=&client_id=theClientIDFromHelpDesk&client_secret=theClientSecretFromHelpDesk&grant_type=password" -X POST -k https://services.cancerimagingarchive.net/nbia-api/oauth/token

Example Request for a Token for a Specific User to Access Private Collections

Most data in TCIA are fully public. However, certain collections require special permissions to access them. To access these collections, you must first register for a TCIA account (be sure to scroll down on this page and click "CLICKING HERE" to accept the terms and conditions) and then contact the TCIA Help Desk for permission to access the restricted data. The TCIA Help Desk will also give you the client_id and client_secret. An example follows that shows how to request NBIA REST services for restricted data.

# Request for token for a specific user to access restricted data
          
$ curl -X -v -d  "username=MyUsername&password=MyPassword&client_id=theClientIDFromHelpDesk&client_secret=theClientSecretFromHelpDesk&grant_type=password" -X POST -k https://services.cancerimagingarchive.net/nbia-api/oauth/token

Example of How a Token is Returned/Granted/Given

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

{"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.

# Request for modality values           
$ curl -H "Authorization:Bearer f7889076-b3e4-4768-9419-3cd973adda76" -k "https://services.cancerimagingarchive.net/nbia-api/services/v2/getModalityValues" 

A successful service request returns the value in a defined format. The example of the returned result for the preceding service call is as follows. Note that this result may not represent the full list of modalities in the database and is subject to change.

[{"Modality":"CR"},{"Modality":"CT"},{"Modality":"DX"},{"Modality":"HC"},{"Modality":"HISTOPATHOLOGY"},{"Modality":"MR"},{"Modality":"PR"},{"Modality":"PT"},{"Modality":"RTDOSE"},{"Modality":"RTPLAN"},{"Modality":"RTSTRUCT"},{"Modality":"SC"},{"Modality":"SR"},{"Modality":"US"},{"Modality":"XA"} {"Modality":"CTPT"}{"Modality":"FUSION"}{"Modality":"KO"}{"Modality":"MG"}{"Modality":"REG"}{"Modality":"RWV"}{"Modality":"SEG"}]

Example Request for Refreshing the Token

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

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

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

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

Example Request for Logout

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

The result:  

 You Have Logged Out successfully.

Drill Down API

The Drill Down API provides the functionality in the search client where the user drills down the studies and series associated with a given patient.

The API takes a list of series to query, using the parameter "list," that repeats for each series you want to retrieve. During the workflow these values come from the series identifiers in the Extended Simple Search with Modality and Body Part Paged Query.

Example Drill Down Query 

curl -H "Authorization:Bearer 946bddb4-d076-4fb1-8dff-81fb64d6f921" -k "https://services.cancerimagingarchive.net/nbia-api/services/getStudyDrillDown" -d "list=1376256&list=262144"

The Drill Down API returns JSON with the information to populate the drill down to study screen. There can be multiple studies.

    "exactSize" : 4739336  } ]} ]

Drill Down Using Series UIDs API

The Drill Down Using Series UIDs API provides the functionality in the portal where the user drills down the studies and series associated with a set of IDs.  In this case, the API takes Series Instance UIDs so the users can access this information outside of the Search Client workflow using any Series Instance UIDs that they are interested in.

The API simply takes a list of Series UIDs to query, using the parameter "list," that repeats for each Series UID you want to retrieve.

Example Drill Down Using Series UIDs Query 

curl -H "Authorization:Bearer 5e3e2193-55dc-43b5-b11a-70fee2ccf50f" -k "https://services.cancerimagingarchive.net/nbia-api/services/getStudyDrillDownWithSeriesIds" -d "list=88.8.327219764444138790630242591550292040652&list=88.8.48940758713094405889891485363115655700"

The Drill Down Using Series UIDs API returns JSON with the information to populate the drill down to study screen. You can retrieve multiple studies.
