Overview
The Cancer Imaging Archive )TCIA) is a publisher of cancer related data. Each Collection is issued a Digital Object Identifier (DOI) through DataCIte. DataCIte provides a REST API that can be used to search metadata according to their published schema. Please note that this API was not developed by TCIA and is not supported through the TCIA help desk.
Please refer to the Documentation below for how to use the DataCite REST API to query TCIA metadata

Examples
Retrieve a single DataCite record in JSON format. For this example we are using a Published Collection called "Pseudo-PHI-DICOM-Data"
Return a list of DOIs using the TCIA provider id (tciar)
https://api.datacite.org/dois?provider-id=tciar
By default, only 25 records are returned. You can control the number of records returned using pagination options. For example, to return only 5 records
https://api.datacite.org/dois?provider-id=tciar&page[size]=5
or
Query on specific information populated in the DataCite schema, for instance return the records published by The Cancer Imaging Archive that were published in 2016
or
Use the "activities" endpoint to see metadata updates in JSON format for a specified DataCite record. For this example we are using a Published Collection called "Pseudo-PHI-DICOM-Data"
