OCT: Optical Biopsy and Other Applications

Optical coherence tomography (OCT) is an emerging medical imaging technology that can perform high-resolution, cross-sectional imaging of tissue morphology in situ and in real time.[1] OCT imaging is analogous to ultrasound, except that it uses light instead of sound. Measurements are performed by directing a beam of light onto tissue and measuring the echo time delay and magnitude of reflected or backscattered light using low-coherence interferometry.
