Abstract

Where OCT imaging provides high-resolution structural images in depth, dynamic OCT approaches can provide functional information. OCT signal can be divided in three categories: Static scatterers (structural OCT), flowing scatterers and scatterers entering and exiting the imaged volume. By using the signal acquired at the same position at different times, the static and flowing signals can be differentiated. Dynamic OCT has shown promising results notably in angiography [1,2] and cell activity imaging in organoids [3,4]. Using a Point-Scan Spectral Domain OCT to achieve a resolution close to cell size, a preliminary comparison of different dynamic OCT processing has been conducted to prepare further work in biological tissues.
