The image data in The Cancer Imaging Archive (TCIA) is organized into purpose-built collections. A collection typically includes studies from several subjects (patients).  In some collections, there may be only one study per subject. In other collections, subjects may have been followed over time, in which case there will be multiple studies per subject. The subjects typically have a disease and/or particular anatomical site (lung, brain, etc.) in common.
