The work presented in this paper is being carried on in the framework of the INFN MAGIC-5 (Medical Applications in a GRID Infrastructure Connection) project, whose goal is the development of software for medical applications as Computer Aided Detection (CAD) Systems and distributed databases to be implemented in a GRID Virtual Organization. In particular, here we describe the two initial steps of a CAD system for malignant nodule detection in lung Computed- Tomography (CT) images, namely the automated extraction of the pulmonary parenchyma and the following analysis of the pulmonary region for nodule detection.
