Metadata

This collection contains a great deal of supporting documentation that was generated by members of the LIDC. It can be found on the Lung Image Database Consortium research page. A subset of the metadata (XML annotation/markup info) is also contained along side the images in TCIA and will be automatically downloaded with the images unless specified to be excluded.
