Optical Coherence Tomography

Optical Coherence Tomography

Optical Coherence Tomography (OCT) is a non-invasive imaging technique that uses light waves to capture detailed, cross-sectional images of biological tissues. It is widely used in medical fields such as ophthalmology, cardiology, and dermatology to visualize internal structures in high resolution.

OCT uses low-coherence light to measure the echo time delay and intensity of light reflected from internal tissue structures. The process is somewhat similar to ultrasound imaging, but instead of sound waves, it uses light. This allows OCT to provide micrometer-scale resolution, making it ideal for viewing fine tissue layers.
