Abstract

Μέθοδος απεικόνισης για να παρατηρείται η διάδοση παλμικού κύματος διάτμησης χαμηλής συχνότητας ταυτόχρονα σε πολλαπλά σημεία ενός διαχέοντος ιξώδους ελαστικού μέσου (1). Προς τον σκοπό αυτό, εκπέμπονται σε πολύ υψηλή ταχύτητα υπερηχητικά κύματα συμπίεσης που επιτρέπουν την λήψη διαδοχής εικόνων του μέσου, κατόπιν επεξεργάζονται ετεροχρονισμένα οι εικόνες που προκύπτουν με συσχέτιση μεταξύ τους για να προσδιοριστούν σε κάθε σημείο κάθε εικόνας οι κινήσεις του μέσου κατά την διάδοση του κύματος διάτμησης.
