You can find a list of all collections on the TCIA home page: http://www.cancerimagingarchive.net. The middle window on this page is labeled "TCIA Collections". It contains a list of all collections in TCIA. The orange "Search TCIA" button takes you to the TCIA search page. Typing anything into the "Filter table" input box will restrict the list of collections to those which match the pattern in the box. To access detailed information about a collection, click the link in the "Collection" column. This will take you to a page in the wiki with detailed information about the collection.
You can reference the corresponding wiki pages for any particular collection when you are logged into TCIA. From the search page, in the collection area, mouse over and click on the question mark symbol for information on each collection. If there is a wiki available for the collection, click it.
To access a restricted collection, you can gain approval by calling or texting the Help Desk at +1 385-275-8242 (+1 385 ASK-TCIA), or send an email to firstname.lastname@example.org. Please indicate the name of the restricted collection.

Using MRI images of the prostate as an example, follow the steps below to download images from a specific collection:
Click the cart icon for one or more series. If you select only some of the series, the cart turns yellow. If you select all of the series, the cart turns green. The number of image series in your cart also appears next to the cart.
The cart itself, in the upper-right of the window, shows how many image series are in it and how large the download will be.
A message appears reminding you to download the NBIA Data Retriever. If you have already downloaded it, click Do not show this message again and click . Otherwise, click to go to a page with links for downloads for each operating system.
manifest-xxx.tciafile in the NBIA Data Retriever. For more information on the NBIA Data Retriever, see NBIA Data Retriever FAQ. Also see question #1 in the previous section.
The National Biomedical Imaging Archive (NBIA) software enables searching for images in TCIA’s local in vivo image repository. For simple searches, see Performing a Simple Search. For text searches, see Performing a Text Search (these links are in the TCIA User's Guide) for more detailed instructions.
If your query is too restrictive, the search will return no results. Try starting with one criterion and add additional criteria one at a time to refine your search.
As you review search results in TCIA, you can add items at any level to your cart for subsequent download. You can then view subject details, thumbnails of the image series, and DICOM headers.
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.
You can save your query for later use or share it with a colleague by email.
Collection descriptions provide information about what disease was studied. On the Search Images page, scroll down to the collections block and click the question mark to the left of the collection name. Click to see a brief description of the collection; it will usually have pointers to a site where more detailed information about the collection is available.
The NBIA software enables you to search for images in TCIA's image repository in a variety of ways. Although searching for a particular collection is the most common, you can also search for the images belonging to one or more subjects. Simply start on the Search page and enter one or more subject ID strings, separated by commas.
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.
The legacy Download Manager permits downloading of DICOM images only. To capture a large number of images, download them in DICOM and then reference the websites below for assistance with utilities that will convert DICOM images to other formats.
To download only a single image (or a handful of images one at a time):
The .XML files are in the series folder since they are related to the images in that series. You can find the annotated files by viewing the list of files in a given folder.
Java version 6 or higher of the Java Runtime Environment (JRE) must be installed to be able to open the Download Manager. See Download Manager for more information.
The number of series that can be downloaded using Download Manager is dependent on several factors: average image size, RAM on your computer, free disk space on your computer, network speed, and Java limitations. If you experience issues or errors associated with the download, reduce the number of series in your basket and try again.
If you never even see the Download Manager GUI, and Java reports that the Download Manager failed to launch, you may be running an old version of Java, and/or your Java application cache may be stale and needs to be cleared. See Clearing the Java Application Cache for instructions on how to clear the cache.
In some cases, the first attempt to run Download Manager on a computer might fail. Please simple retry launching the download manager (i.e., click on the "Download Manager" link on the shopping cart page). If the error persists, please contact TCIA's helpdesk at firstname.lastname@example.org , letting them know what computer, operating system version of Java that you are using. You can find instructions for determining this information at this link (click here).
Accessing TCIA’s Download Manager directly through a proxy server is currently not supported. If your only access to the Internet is through a proxy server, our current recommendation is to ask your IT Department to allow your workstation to bypass the proxy server for direct access to https://public.cancerimagingarchive.net/ncia.
Java may be configured to utilize proxy settings; however, the developers of NBIA have not tested whether Download Manager correctly handles such settings.
Theoretically, yes. However, we principally test with Firefox, Chrome, and Internet Explorer. We also test with Safari (the default browser on most Macs), and it did work up to version delivered on Mac OS X version 10.8.3 (Mountain Lion). After 10.8.3, Safari will silently download the JNLP file used to launch the Download Manager, but will not automatically start the Download Manager program. Safari does not give the user any warning, so to the casual user it appears that the Download Manager link is broken. One has to go to the Downloads folder, find the JNLP file just downloaded, and then command | control | right click the JNLP file and select "Run" from the pop-up context menu to start the Download Manager.
Some browsers on some operating systems do not have our Certificate Authority in their list of trusted root Certificate Authorities. In these cases, the browser may present a warning about not trusting the connection to the web site. You may still be able to download images by clicking on the "Continue" or similar button.
In theory, the Download Manager, being Java based, will work on any operating system. However, the Mac OS X operating system has been imposing additional security requirements on Java Web Start programs, such as the Download Manager, which make it difficult to run them without having administrative access to the Mac. In particular, the Gatekeeper function in 10.8.4 (Mountain Lion) and later versions of Mac OS X by default blocks starting third party programs that have not been either obtained from the Apple App store, or that have not been signed with an Apple Developer ID. This includes, naturally, Java Web Start programs such as the Download Manager. To get around this restriction, one can either change the default Gatekeeper setting, found in the Security tab of Apple System Preferences, to allow the running of 3rd party applications, or download the JNLP file used to launch the Download Manager, and then command | control | right click the JNLP file and select "Run" from the pop-up context menu. Note that either method requires either having administrative access to the Mac OS, or knowing the username/password of an administrator account, since the Mac will prompt for this information.
Our support team needs the following information to perform additional troubleshooting:
1. A screen capture of the error message.
2. A screen capture of the Java console (you may need to enable viewing the Java console using the Control Panel > Java Control Panel > Advanced > Settings: Java Console > Show Console).
3. Operating system and version.
4. Browser and version.
Theoretically, there is no maximum number of series that Java allows Download Manager to hold in a single shopping cart. However, it is not practical to download more than around 3500 series at one time. The number of series in your basket will display on the left navigator at the top under My Data Basket > View Contents.
When downloading images the default destination location for Windows devices is a path that is hidden by default which makes it hard to locate after the download completes. We suggest clicking the "Browse" button and selecting a more convenient destination for your data.
Please refer to The Cancer Genome Atlas-Glioblastoma Multiforme (TCGA-GBM) collection for well-documented brain-tumor images as described here: https://wiki.cancerimagingarchive.net/display/Public/TCGA-GBM. (This wiki page also links to pages describing related research activities and related resources.)
In the Related Data section, there is a link to a blank GBM Case Quality Control Form that details the kinds and descriptions of clinical data collected. The data are freely available from the TCGA Data Portal: https://tcga-data.nci.nih.gov/tcga.
Once there, click on the link to GBM data. Since TCIA does not host the TCGA Data Portal, we do not offer guidance for browsing the Data Portal.
The TCGA-Lower Grade Glioma (LGG) collection is another set of brain tumor images: TCGA-LGG.
All patients who are part of TCIA at this time are cancer-positive by definition. We have no collections of non-malignant tumors or healthy patients. The only exception would be patients with multiple tumors who might have a benign tumor in addition to a malignant tumor, but at least one tumor will be malignant in each patient.
Access to NLST images and data requires approval of the National Cancer Institute (NCI). For details, please see: https://biometry.nci.nih.gov/cdas/studies/nlst.

Our technical support team may ask you to answer these three questions if you're having difficulty with our website:
Which operating system are you using? (Typical examples would be Windows8, Mac OSX, Redhat Linux)
To find your OS, browser, and java version, you may find the guide at Discover your OS Browser and Java Version helpful. The next step would be to test the site (but not necessarily click "download my basket") on another machine like a home laptop, to see if perhaps your institution has set, for example, a special layer of security on its network. The next step would be to email email@example.com to schedule an appointment for a webex teleconference with our technical support team to work with you interactively to facilitate access.
