These links help describe how to use the .XML annotation files which are packaged along with the images in the Cancer Imaging Archive. The option to include annotation files in the download is enabled by default, so the XML described here will be included when downloading the LIDC-IDRI images unless you specifically uncheck this option. Please note that it is not currently possible to visualize this annotation and markup on top of the images themselves. The Cancer Imaging Program is exploring the possibility of converting this XML into AIM format so that it could be visualized in AIM compatible workstations, but no definite plans are in place at this time.
