These are the devices that help to recognize useful signals, which are reflected by optical inhomogeneity in the depth of the objects under study. The use of OCT presupposes application of fiber interferometers, which are characterized by high sensitivity. Simply put, the information about morphological structure peculiarities of transparent tissues is contained on the optical tomograms. In the course of research, conducted with the help of coherence tomographs, the specialists obtain data forming 2-dimensional cards of reverse reflections of optical microinhomogeneities of cellular tissue structures. As a result, a lateral unfolding of OCT-images is obtained. It is done with the help of a special probing beam. Along with the depthwise scanning, the scanning across the tissue surface is conducted during tomography process. As a result, its reflection on the internal microstructures of the tissues on different depths is obtained. The probing radiation beam is concentrated on the tissues, while the interferometric measurement of the echo delay of the probing radiation is conducted. However, the ophthalmic analogue uses optical radiation of the closest range of the infrared type instead of soundwaves for tissue probing. Types of Optical coherence tomographsĪ coherence tomograph resembles an ultrasound machine by its operation principle. The obtained images are characterized by high indices of spatial resolution. Optical coherence tomography is a type of ophthalmic research with the help of which the doctor gets the scans of optically transparent eye tissues. OCT is used to conduct the necessary research and diagnosing. Where Optical coherence tomography are Used?Ī lot of machines, methods and ultramodern techniques are used in modern ophthalmology in order to treat eye diseases.
