Abstract

Speichermedium, das Anweisungen umfasst, die, wenn sie durch einen Prozessor ausgeführt werden, ein System veranlassen einen Satz von Vorgängen durchzuführen, wobei der Satz von Vorgängen umfasst:Zugreifen auf einen Satz von Bildgebungsdaten, einschließlich erster Bildgebungsdaten für einen ersten Zeitpunkt, zweiter Bildgebungsdaten für einen zweiten Zeitpunkt und dritter Bildgebungsdaten für einen dritten Zeitpunkt;Identifizieren einer ersten Stelle einer Region von Interesse (ROI) in den ersten Bildgebungsdaten;Identifizieren einer zweiten Stelle der ROI in den zweiten Bildgebungsdaten;Identifizieren einer dritten Stelle der ROI in den dritten Bildgebungsdaten;Bestimmen einer Vielzahl von Differenzen zwischen den identifizierten Stellen, wobei die Vielzahl von Differenzen eine Differenz einschließt zwischen:der ersten Stelle und der zweiten Stelle;der ersten Stelle und der dritten Stelle; undder zweiten Stelle und der dritten Stelle;basierend auf der bestimmten Vielzahl von Differenzen, Auswählen eines von den ersten Bildgebungsdaten, den zweiten Bildgebungsdaten oder den dritten Bildgebungsdaten als Referenz-Bildgebungsdaten für die Bewegungskorrektur; undDurchführen einer Bewegungskorrektur für den Satz von Bildgebungsdaten mit dem ausgewählten Referenzbild.
