Abstract

M5L, a Web-based fully automated Computer-Aided Detection (CAD) system for the automated detection of lung nodules in thoracic Computed Tomography (CT), is based on a multi-thread analysis with two independent CAD subsystems, the lung Channeler Ant Model (lungCAM) and the Voxel-Based Neural Analysis (VBNA), and on the combination of their results. The lungCAM subsystem is based on a model of the capabilities that ants show in nature in finding structures, defining shapes and acting according with local information. The VBNA subsystem is based on a multi-scale filter for spherical structures in searching internal nodules and on the analysis of the intersections of surface normals in searching pleural nodules. The M5L performance, extensively validated on 1043 CT scans from 3 independent datasets, including the full LIDC/IDRI database, is homogeneous across the databases: the sensitivity is about 0.8 at 6-8 False Positive findings per scan, despite the different annotation criteria and acquisition and reconstruction conditions. A prototype service based on M5L is hosted on a server operated by INFN in Torino. Preliminary validation tests of the system have recently started in several Italian radiological institutes.
