NIH | National Cancer Institute | NCI Wiki  

A simple search allows you to search for image studies based on a combination of the following search filters: Collections, Image Modality, Anatomical Site, Date released on TCIA, and Subject IDs. The more criteria you select, the fewer results you receive. After you select your search criteria, you can save your query to use later.


To perform a simple search

  1. On the NBIA home page, click the Simple Search tab. 
    The Simple Search page appears.
    Summary page that displays after logging in
  2. Select filters to narrow down the available image series.

    To SelectDo This
    Collections

    Option 1: Click the box next to each collection name you want to select.

    4D-Lung Collection selected

    Hovering over a collection name opens a window with information about the collection in it. Quickly move your mouse to this window, were you can select text and click links. The window stays open until you move your mouse away from it. 

    4D-Lung This data collection consists of images acquired during chemoradiotherapy of 20 locally-advanced, non-small cell lung cancer patients. The images include four-dimensional (4D) fan beam (4D-FBCT) and 4D cone beam CT (4D-CBCT). All patients underwent concurrent radiochemotherapy to a total dose of 64.8-70 Gy using daily 1.8 or 2 Gy fractions.  A single Radiation Oncologist delineated targets and organs at risk in all 4D-FBCT and a limited number of 4D-CBCT images. All patients underwent concurrent radiochemotherapy to a total dose of 64.8-70 Gy using daily 1.8 or 2 Gy fractions.  Please see the 4D-Lung wiki page to learn more about the images and to obtain any supporting metadata for this collection.


    Option 2: Click the magnifying glass to enter a name.

    Image Modality

    Click the box next to one or more image modalities.

    If you select more than one image modality, clicking ANY returns any study that is associated with any of the modalities you selected. Clicking ALL returns all studies that are associated with all of the modalities you selected.

    When you select the ANY search modifier here, only the studies that match your search criteria are returned. Be aware that these may be only be a subset of the studies belonging to a single subject (patient). The potential difference between total studies available and the number of studies returned by your search becomes clearer when you select the Total Studies and Total Series columns to appear in your search results. To do so, click at the top of the Search Results tab. Select Total Studies and Total Series in the Pick Columns list.

    Pick columns list of choices, which includes Cart, Collection ID, Subject ID, Studies, Total Studies, Series, and Total Series.

    Anatomical Site

    Click the box next to each anatomical site you want to select.

    Species

    Click the box next to the species you want your search results to represent, either human or Mus musculus (mouse).

    Phantoms

    Click the box next to the phantom option you want to select.

    Phantoms search filter. Options are Only Phantoms, Exclude Phantoms, and Include Phantoms.

    At least X time point (DICOM studies)

    Enter the minimum number of time points that match the criteria of your search. This filter allows you to see subjects that have more than one DICOM study (that is, the patient was seen at multiple time points).

    At least X (number) time point (DICOM studies) field

    3rd-Party Analysis Results

    3rd-party analysis results are derived data (e.g. segmentations) that were contributed by researchers who were not part of the group that originally submitted a collection to TCIA.

    Click the box next to each third-party analysis results option you want to select. Only DICOM data from third-party analysis results appear when using this search filter. A full listing of all third-party analysis data inclusive of non-DICOM formats can be found in the Analysis Results Directory.

    At least X time point (DICOM studies)

    Enter the minimum number of time points that match the criteria of your search. This filter allows you to see subjects that have more than one DICOM study (that is, the patient was seen at multiple time points).

    At least X (number) time point (DICOM studies) field

    Date Released

    Enter a From and To date to narrow your search results to studies first made available during that date range.

    Alternately, select the Apply "Available" date range box to exclude studies that were unavailable during the selected date range.

    Subject IDs

    Enter Subject IDs associated with the image series you want to receive in your search results. Separate each Subject ID with a comma and then click Apply Subject IDs.

    Apply Subject IDs

  3. Select which columns you want to have appear in the detailed search results on the Search Results tab by clicking at the top of the Search Results tab. The Pick Columns panel appears. 

    Pick columns list of choices, which includes Cart, Collection ID, Subject ID, Studies, Total Studies, Series, and Total Series.

    Search results are shown in two different ways, as a summary and as detailed search results, and which one appears first matches your last choice. The Summary tab shows updated pie charts and the number of image series in the search results.
