Application of optical coherence tomography in biomedicine
Abstract: Optical coherence tomography is a new 3D tomography technology developed in the 90 time in twentieth century. OCT is based on the principle of low coherence interferometry, and can reconstruct 2D or 3D images of the structure of biological tissues or materials by scanning.The signal contrast is derived from the spatial variation of optical reflectance (scatter) in biological tissues or materials. which can get high-resolution images of tissue structure, and has prominent advantages such as non-contact, no harm, biopsies.Contrast to other detection methods, because of the significant advantages of OCT ,it has unparalleled advantage in biomedicine, so that OCT has been widely used in the field of ophthalmology, cardiovascular medicine. Firstly, definition, classification, characteristics and development of OCT are analyzed. Secondly, on the basis of the previous study, theoretical principles of light propagation model characteristics and OCT systems in biological tissue are analyaed. Finally, the application of OCT technology in all areas of medical are researched.
