What OPTICAL COHERENCE TOMOGRAPHY (OCT) means: A technique for obtaining sub-surface images such as diseased tissue just below the skin. For example, ophthalmologists use OCT to obtain detailed images from within the retina. Cardiologists also use it to help diagnose coronary artery disease.
- Definition Optical Imaging:
- Dictionary invasively looking inside the body, as is done with x-rays. Unlike x-rays, which use ionizing radiation, optical imaging uses visible light and the special properties of photons to obtain detailed optical coherence tomography (oct).
