Abstract

Παρέχεται ένα σύστημα και μια μέθοδος για τη χρήση δεδομένων οπισθοσκέδασης και γνωστών παραμέτρων για τον χαρακτηρισμό του αγγειακού ιστού. Συγκεκριμένα, σε μια εφαρμογή της παρούσας εφεύρεσης, χρησιμοποιείται μια συσκευή υπερήχων (120) για την απόκτηση δεδομένων οπισθοσκέδασης RF (δηλ. δεδομένων IVUS) από ένα αιμοφόρο αγγείο. Τα δεδομένα IVUS στη συνέχεια μεταδίδονται σε μια υπολογιστική συσκευή (130) και χρησιμοποιούνται για να δημιουργήσουν μια εικόνα IVUS. Το αιμοφόρο αγγείο κατόπιν διατομώνεται και χρησιμοποιείται για τον προσδιορισμό του τύπου του ιστού και για τη δημιουργία μιας αντίστοιχης εικόνας (δηλ., της ιστολογικής εικόνας). Μία περιοχή ενδιαφέροντος (ROI). που κατά προτίμηση αντιστοιχεί στον προσδιορισμένο τύπο ιστού, προσδιορίζεται στη συνέχεια στην ιστολογική εικόνα. Η υπολογιστική συσκευή (130), ή ειδικότερα μία εφαρμογή χαρακτηρισμού (132) που λειτουργεί επ' αυτής, προσαρμόζεται έπειτα για να προσδιορίσει μια αντίστοιχη περιοχή στην εικόνα IVUS. Ωστόσο, για την ακριβή αντιστοίχιση της ROI. μπορεί να χρειαστεί να σκεβρωθεί ή να μορφοποιηθεί η ιστολογική εικόνα ώστε να προσαρμοστεί ουσιαστικά στο περίγραμμα της εικόνας IVUS. Αφού προσδιοριστεί η αντίστοιχη περιοχή, αναγνωρίζονται τα δεδομένα IVUS που αντιστοιχούν σε αυτήν την περιοχή. Στη συνέχεια εκτελείται επεξεργασία σήματος και προσδιορίζεται τουλάχιστον μία παράμετρος. Η προσδιορισμένη παράμετρος και ο τύπος ιστού (π.χ. δεδομένα χαρακτηρισμού) αποθηκεύονται σε μια βάση δεδομένων (134).
