Introduction to the NBIA Data Portal

NBIA Data Portal enables you to search for images in the local NBIA in vivo image repository. If available, you can also search remote imaging archives.

NBIA 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 NBIA 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.

Searching for Image Studies

You can search and download public data without logging in to the NBIA Data Portal. To access restricted data, however, you must log in first to see that data in your search results.

NBIA provides two ways to search for image studies:

When you first open NBIA Data Portal, the Summary tab displays filters for a simple search and pie charts.

Summary page that displays after logging inImage Added

Click one or more boxes next to each search filter to select it. As you select search filters, they move to the top of the list. They also appear in Boolean query format above the pie charts. This query specifies the filters you have applied to your search. Click Clear if you want to remove all of your filters at once and start over. You can save your query as a URL for later use or to put in an email to a colleague. For more information about sharing, go to NBIA Data Portal User Guide-deleteNBIA Data Portal User Guide-delete.

You can filter (narrow) your search by Collections, Image Modality, Anatomical Site, Species, Phantoms, 3rd-Party Analysis Results, Date Released, and Subject IDs. You can also specify the minimum number of image studies you want to match each search filter. For Collections, if you know the name of the collection, click Magnifying glassImage Added to enter it instead of finding and clicking the collection's box.

The Simple Search page shows a summary of image studies that match your search criteria. Your selections appear in the following ways:

  • Boxes you selected are checked.
  • Pie charts update to show the exact search results.
  • Breadcrumb-style labels at the top of the page show the applied search filters (not all may display due to space constraints).
  • Count of search results appears.

Simple Search page with filters, Collections, and Image ModalitiesImage Added

The pie charts show the count of image studies in your search results by Collection, Image Modality, and Anatomical Site. Click a pie slice or hover over it to see the name of the Collection, Image Modality, or Anatomical Site, and number of each, in your search results.

Count by Collections pie chart with Selected filter and Filter NameImage Added

The Search Results tab shows the same results as the pie charts but in tabular form.

Search results in tabular formatImage Added

Text searches involve entering any text that might appear in any search filter.

Text SearchImage Added

Results are displayed in pie charts and a table, just as with the simple search.

Accessing Limited-Access Collections

You can search and download public data without logging in to the NBIA 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.

Viewing Subject Details

The search results from your query are presented both on the Summary tab in pie charts and on the Search Results tab in a table. Each record in the table corresponds to one subject (patient) and displays the collection(s), study(ies), and image series associated with that subject.

From the Search Results tab, you can view subject details, view all image series associated with the subject, and add image series to your cart for download. You can also view the DICOM header for a selected image series. In the future, you will be able to view the image.

To view subject details

  1. Search for studies that match criteria that interest you.
    The Summary tab refreshes to show your search results in pie chart form.
  2. Click the Search Results tab.
    The search results that match your criteria appear sorted by Subject ID.

    You can now add all studies associated with a subject to your cart at the same time or drill down to an individual study and add it to your cart instead.

  3. Click a Subject ID link.
    A list of all studies associated with this subject appear. In this example, this subject is only associated with one study, and only one image series is associated with that study.
