A CADx scheme in mammography: considerations on a novel approach

This paper describes a prototype of a complete CADx system developed in the last years in our research groupp. Its basic structure consists of pre-processing corrections based on the image acquisition and digitization procedures (FFDM, CR or film + scanner), a segmentation tool to detect clustered microcalcifications and suspect masses and a classification scheme, which evaluates the presence of microcalcifications clusters and possible malignant nodules based on their contour. The aim is to provide enough information not only on the detected structures but also a prereport with a BI-RADS classification. At this time, the system is still lacking an interface integrating all the modules. Despite this, it is partially functional, as a prototype for testing.
