Abstract

Μέθοδος η οποία περιλαμβάνει την αναγνώριση και απεικόνιση των υλικών σε σύστημα ακτίνων Χ. Βασίζεται στην παραγωγή μιας σειράς εικόνων με χρήση ακτίνων Χ διαφορετικών ενεργειών, ανάλυση και υπολογισμό των χαρακτηριστικών καμπυλών απορρόφησης των ακτίνων Χ του ακτινοβολούμενου όγκου, σε επίπεδο εικονοστοιχείου (pixel) ή ογκοστοιχείου (voxel), καθώς επίσης φυλτραρίσματος και σύγκρισης των καμπυλών με αυτές γνωστών υλικών από σχετική βάση δεδομένων. Τα παραγόμενα αποτελέσματα απεικονίζονται με χρήση μια νέας απεικονιστικής μεθόδου στην οποία οι τιμές των στοιχείων της εικόνας αντιστοιχούν και απεικονίζουν υλικά.
