optical coherence tomography (oct)

How Does OCT Work?

OCT works by emitting a beam of near-infrared light into the tissue. This light is partially reflected back from various layers within the tissue. The reflected light is then compared to a reference beam in an interferometer to generate an interference pattern. This pattern is processed using Fourier-transform algorithms to create a detailed image of the tissue's internal structure. The capacity to differentiate between layers with high resolution is what sets OCT apart from other imaging techniques.
