Adaptive Optics OCT

Definition

Adaptive optics optical coherence tomography (OCT) is an advanced imaging technique that enhances the resolution of OCT by compensating for the optical distortions caused by the eye's structures. This technology allows for clearer and more detailed images of retinal tissues, making it invaluable in ophthalmology and other biomedical applications. By utilizing adaptive optics, this method improves the ability to visualize fine details in biological tissues, paving the way for better diagnostics and treatment planning.
