The Lung Imaging Database Consortium (LIDC) image collection 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.
For more information about the LIDC program please visit: http://imaging.cancer.gov/programsandresources/InformationSystems/LIDC
These links help describe how to use the .XML annotation files which are packaged along with the images in NBIA.
Annotation and Markup Issues/Comments
This link provides a list of available cases and the associated size of each identified nodule.
For a limited set of cases, LIDC sites were able to identify diagnostic data associated with the case. Data was collected for as many cases as possible and is associated at two levels:
At each level, data was provided as to whether the nodule was:
For each lesion, there is also information provided as to how the diagnosis was established including options such as:
You can download this Diagnosis Data at: LIDC Diagnosis Data-01-08-10.xls
Note: Data is still arriving from the LIDC sites and so in the coming months this spreadsheet will be updated as more information is received
As part of an effort to move towards standard formats for annotation and markup a project has been undertaken to convert this data from the LIDC project into Annotated Image Markup format (AIM). AIM is a standard which was developed out of the caBIG program. A related section of the wiki has been dedicated to covering the activities of this project and can be found here: LIDC Conversion to AIM
