4) A LIBRARY OF LUNG TUMORS THE LUNG IMAGE DATABASE CONSORTIUM AND IMAGE DATABASE RESOURCE INITIATIVE

A database of more than one thousand lung scans, the culmination of a nine-year effort on the part of seven academic institutions and eight medical imaging companies, has been completed and is now available to medical imaging investigators. The project will be presented by Samuel G. Armato III, Ph.D., associate professor of radiology at the University of Chicago, during the 2010 annual meeting of the American Association of Physicists in Medicine, July 18-22, in Philadelphia, PA.

The rationale for the project, according to Armato, was to assist developers of automated detection systems, often referred to as CAD (computer-aided diagnosis) by offering them a "standard of truth" against which to compare their methods. All of the images contained in the database are clinical CT scans (computed tomography) that were read manually by a team of four thoracic radiologists, working in two phases. In the first phase, each radiologist worked independently of the others; in the second phase, they reviewed one another's findings in order to achieve a more complete read of each scan.

The database contains 1018 CT scans and a total of 7371 identified lung nodules, as well as the radiologists' markings of the larger nodules' outlines and characteristics, including subtle
