Objectives: To benchmark the performance of state-of-the-art computer-aided detection (CAD) of pulmonary nodules using the largest publicly available annotated CT database (LIDC/IDRI), and to show that CAD finds lesions not identified by the LIDC's four-fold double reading process. The LIDC/IDRI database also contains annotations which were collected during a two-phase annotation process using 4 experienced radiologists. The goal is to ensure that when multiple research groups use the same (*) Citation: The equivalent diameter of the nodule, i. e. the diameter of the sphere having the same volume as the nodule estimated volume.
