The Lung Image Database Consortium image collection (LIDC-IDRI) consists of diagnostic and lung cancer screening thoracic CT scans with marked-up annotated lesions. It is a web-accessible international resource for development, training, and evaluation of computer-assisted diagnostic (CAD) methods for lung cancer detection and diagnosis.
Additional information about using this data as well as some collection meta data can be obtained on the Lung Image Database Consortium research page.
You can view and download these images on The Cancer Imaging Archive by logging in to TCIA and selecting the LIDC-IDRI collection.

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.
