OCT verstehen – Teil 2: Praktische Aspekte und Anwendung

Den Schwerpunkt dieses Artikels bildet die Vermittlung praktischen Wissens rund um die optische Kohärenztomografie (OCT). Während in Teil 1 [1] die physikalischen Grundlagen vorgestellt wurden, werden hier praktische Aspekte für den Anwender erläutert, unabhängig vom verwendeten Gerätetyp oder Hersteller.

Grundsätzliche Parameter und Einstellmöglichkeiten werden vorgestellt. Es wird hinterfragt, was ein OCT-Bild eigentlich zeigt und wann bei der Interpretation und Auswertung Vorsicht geboten ist. Typische Artefakte sowie deren Ursachen und Möglichkeiten der Vermeidung werden diskutiert. Zuletzt wird eine Übersicht über aktuelle Anwendungsfelder der OCT in der Augenheilkunde gegeben.
