Significance enhancement of phase-contrast and dark-field signals — •Veronika Ludwig, Jens Rieger, Georg Pelzer, Thomas Weber, Thilo Michel, and Gisela Anton — Friedrich-Alexander-Universität Erlangen-Nürnberg

The topic of my Master thesis is to improve the significance of the phase-contrast and dark-field signals resulting from microcalcifications in mammography images. For that purpose, different methods of statistical image analysis were used. The talk will give an overview of the approaches to improve the SNR and CNR, to reduce uninteresting artifacts like edge effects and to enhance microcalcification structures. Besides the common image processing tools such as median filtering, the application of the gray-level co-occurrence matrix and Minkowski functionals were used. Finally, the results for the best combination of methods are shown and an outlook is given.
