What's New in the TCIA Data Portal
...
Introduction to the TCIA Data Portal
TCIA Data Portal enables you to search for images in the local TCIA in vivo image repository. If available, you can also search remote imaging archives.
TCIA submissions are organized in the following hierarchy, which is important to remember in creating your search query and reviewing search results:
...
Collection > Patient (Subject) > Study > Series > Images
In other words, a Collection is the largest organizing concept within TCIA and it includes data about Patients (also called Subjects). As you continue to drill down to more granular concepts, Patients contain Studies, Studies contain (Image) Series, and Series contain individual Images.
Browser Support
TCIA supports the latest versions of Google Chrome and Mozilla Firefox browsers.

Shared queries honor data permissions that may exist. Each person that runs the shared query will only see search results that he or she is allowed to see. |
Sharing Data in Your Cart
Once you have added data to your cart, you can share it as a URL to a static set of data. When you or a colleague opens the URL in a browser window, the new TCIA Graphical User Interface (GUI) opens to the cart page.
In the legacy TCIA data portal, this was called a shared list. This is a similar concept in the new TCIA GUI.
