The RCL makes available to the Data Coordinating Center (DCC) three representative images of the upper, middle, and lower lung. Each image will provide a view of the right and left lung.
The images have been digitized for incorporation into an image repository that can be accessed over the Internet by researchers. The researchers will not be allowed to view the patient's direct identifiers (name, address, etc.) In fact, no slide will be available to a researcher unless there are at least six patients with similar clinical parameters for the request being made.
The researcher will then be shown a random sample of all of the eligible CT scans with the specified parameters.
This procedure is being implemented to protect the confidentiality of the patient who volunteered to allow CT scan information to be collected for this very important study.
