Introduction of Optical coherence tomography
Optical coherence tomography (OCT) could be a non-invasive imaging procedure that employments light waves to deliver high-resolution, three-dimensional pictures of tissues and organs. Optical coherence tomographyworks by emanating a bar of light that’s part into two ways – one that reflects off the tissue and another that voyages to a reference reflect. The reflected light from the tissue and reference reflect is at that point recombined and analyzed to deliver an image.
Optical coherence tomography is commonly utilized in ophthalmology to imagine the retina and analyze conditions such as macular degeneration and glaucoma.
