OCT Technique - Optical Coherence Tomography

OCT - Optical Coherence Tomography is a light based catheter which acquires on an image (photo) inside the heart blood vessel. OCT is a recently-developed, catheter-based Intravascular Imaging Technology that provides micron-scale resolution. It is a laser light equivalent of ultrasound imaging, measuring the intensity of backscattered infrared light rather than sound waves, and translates these optical echoes into a high-resolution, two-dimensional tomographic image. OCT has the highest imaging resolution of any currently-available technology. Cross-sectional resolutions of catheter-based OCT systems are in the range of 10-20 µm.
