What is the difference? New machines have never been used. Besides, one should understand that new and demo optical coherence tomography machine will cost more than refurbished or used oct. The more famous the brand the more expensive the machine, as the brand name itself says a lot about the quality and longevity.Heidelberg,Zeiss ,Optovue, Tomey are considered to be the most well-known. The manufacturer plays a crucial role in making up the oct machine price. The prices of some instruments can be as low as 8000 USD or less, while the newest, high-tier systems may cost as much as 70000 USD. optical coherence tomographs used for scanning of anterior eye sections.devices designed for scanning of posterior eye sections.When equipping a clinic or an ophthalmic consulting-room one should make a responsible choice of an OCT device. speed of obtaining of data about the tissues under study.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.
