Dynamische OCT − was verraten uns die Gefäße?

Abstract: ZusammenfassungDie Weiterentwicklung der optischen Kohärenztomografie (OCT) zur dynamischen OCT (D-OCT) erlaubt die gleichzeitige Darstellung der oberflächlichen Blutgefäße. Blut ist das wichtigste Transportsystem unseres Körpers, und sowohl durch äußere als auch durch innere Einflüsse können physiologische Prozesse beeinträchtigt werden. Die D-OCT ermöglicht erstmals die Darstellung dieser Veränderungen anhand der Gefäßdichte und Durchblutung. Durch wiederholtes schnelles Messen der gleichen untersuchten Regi… Show more

“…A new, pre‐sterilized probe tip was provided for each patient at each visit 7 . The image resolution is <7.5 μm in the lateral and <5 μm in the axial direction 5 . The focal depth is 1–2 mm, but the D‐OCT function is limited to a depth of 0.5 mm because of the speckle noise/signal ratio in the deeper parts of the skin 7,12 .…”

“…D-OCT allows simultaneous visualisation of superficial blood vessels through detection of moving blood cells. 5,12,13 It permits imaging of capillaries (20 μm diameter) and enables to examine the perfusion of the mid/upper dermis, the vascular supply of the wounds.…”
