The Continuous Motion Technique for a New Generation of Scanning Systems.

In the present paper we report the development of the Continuous Motion scanning technique and its implementation for a new generation of scanning systems. The same hardware setup has demonstrated a significant boost in the scanning speed, reaching 190 cm/h. The implementation of the Continuous Motion technique in the LASSO framework, as well as a number of new corrections introduced are described in details.

GPCALMA: implementation in Italian hospitals of a computer aided detection system for breast lesions by mammography examination.

We describe the implementation in several Italian hospitals of a computer aided detection (CAD) system, named GPCALMA (grid platform for a computer aided library in mammography), for the automatic search of lesions in X-ray mammographies. GPCALMA has been under development since 1999 by a community of physicists of the Italian National Institute for Nuclear Physics (INFN) in collaboration with radiologists. This CAD system was tested as a support to radiologists in reading mammographies.

A massive lesion detection algorithm in mammography.

A new algorithm for massive lesion detection in mammography is presented. The algorithm consists in three main steps: 1) reduction of the dimension of the image to be processed through the identification of regions of interest (roi) as candidates for massive lesions; 2) characterization of the RoI by means of suitable feature extraction; 3) pattern classification through supervised neural networks. Suspect regions are detected by searching for local maxima of the pixel grey level intensity.

Comparison of standard reading and computer aided detection (CAD) on a national proficiency test of screening mammography.

Objective: To evaluate the role of computer aided detection (CAD) in improving the interpretation of screening mammograms

Material And Methods: Ten radiologists underwent a proficiency test of screening mammography first by conventional reading and then with the help of CAD. Radiologists were blinded to test results for the whole study duration. Results of conventional and CAD reading were compared in terms of sensitivity and recall rate.
