Computer-aided detection (CAD) of nodules in chest computed tomography (CT) scans has attracted massive interest in the last eight years. There are now multiple commercial systems on the market and a large number of papers have been published that describe systems developed in academia. ANODE09 is an initiative to compare systems that perform automatic detection of pulmonary nodules in chest CT scans on a single common database, with a single evaluation protocol. Data is provided by the Nelson study, the largest CT lung cancer screening trial in Europe. Any team, whether from academia or industry, can join.
On this website, teams can register to participate in the study. After registration, they can download an example dataset of 5 annotated scans and a test set of 50 scans without annotations. Results of CAD systems on those test scans, consisting of a list of locations in the scans and a degree of suspicion that this location is a nodule, can be submitted. The submitted results will be processed and immediately published on-line on the results page.
A special session devoted to the ANODE09 study was held at the 2009 CAD Conference of SPIE Medical Imaging and a joint paper with the first results of the study has been accepted by Medical Image Analysis:
