What OPTICAL IMAGING means: A technique for non-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 images of organs and tissues as well as smaller structures including cells and molecules.
- Definition Optical Coherence Tomography (OCT):
- Dictionary 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 optical imaging.
