30 March 2007An automated system for lung nodule detection in low-dose computed tomography
A computer-aided detection (CAD) system for the identification of pulmonary nodules in low-dose multi-detector helical
Computed Tomography (CT) images was developed in the framework of the MAGIC-5 Italian project. One of the main
goals of this project is to build a distributed database of lung CT scans in order to enable automated image analysis
through a data and cpu GRID infrastructure.
The basic modules of our lung-CAD system, a dot-enhancement filter for nodule candidate selection and a neural
classifier for false-positive finding reduction, are described. The system was designed and tested for both internal and
sub-pleural nodules. The results obtained on the collected database of low-dose thin-slice CT scans are shown in terms of
free response receiver operating characteristic (FROC) curves and discussed.
