Topics on this page describe how to search the local and remote image databases for images.
You can print and export wiki pages. |
Topics in this chapter include:
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.
TCIA supports the latest versions of Google Chrome and Mozilla Firefox browsers.
You can search and download public data without logging in to the TCIA Data Portal. To access restricted data, however, you must log in first to see that data in your search results. Consult the TCIA Collections page to learn which collections have limited access.
Digital Imaging and Communications in Medicine (DICOM) is a standard for handling, storing, printing, and transmitting information in medical imaging.
You can view the DICOM tags that form the header of the selected image series.
To view DICOM data
You can download items you add during the current work session. Before you download items you must download and then install the NBIA Data Retriever.
You select items to download by first searching for them in TCIA and then adding them to your cart.
You can also export data in your cart to a spreadsheet.
To install the NBIA Data Retriever on Windows
To install the NBIA Data Retriever on Mac
The Mac version of the NBIA Data Retriever is only available through the iOS App Store. It requires a manifest file to work. You can download the app first or create a manifest file first. If you download the app first, right-click the manifest file and select Open With Downloader App. If you create a manifest file first, right-click it and select Open With App Store. This installs the app and then opens the manifest file in the app. |
On your Mac, find the NBIA Data Retriever on the Mac App Store.
The NBIA Data Retriever is free but still requires you to log in to download it. Consider changing your iOS Password Settings so that you can download free software without having to log in separately for it. |
To install the NBIA Data Retriever on Linux (centOS or Ubuntu)
You must have the sudo privilege on your computer and a sudo password to install the NBIA Data Retriever on CentOS and Ubuntu.
You can save your query for later use or share it with a colleague by email.
To share a query
Paste the URL into an email or other document.
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. |
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.
To share data in your cart
The shared cart honors data permissions that may exist. Each person that opens the shared cart will only see data that that person is allowed to see. |
