Kohärenztomographie

Kohärenztomographie, also known as optical coherence tomography (OCT), is a non-invasive imaging technique used to visualize the internal structure of biological tissues. It is based on the principles of low-coherence interferometry, which allows for high-resolution imaging with micrometer-scale resolution. OCT is widely used in medical imaging, particularly in ophthalmology, for diagnosing and monitoring eye diseases such as macular degeneration, glaucoma, and diabetic retinopathy. The technique involves emitting a low-coherence light source, typically a superluminescent diode or a femtosecond laser, into the tissue. The backscattered light is then collected and analyzed using an interferometer, which generates a depth profile of the tissue. This profile can be used to create cross-sectional images of the tissue, providing detailed information about its structure and composition. OCT is valued for its ability to provide real-time, high-resolution images with minimal tissue damage, making it a valuable tool in both clinical and research settings.
