1. Optical coherence tomography is one of a class of optical tomographic techniques.2. The needle is an application of an imaging technology called optical coherence tomography . 3. A later method of scanning is optical coherence tomography that also gives 3D imaging. 4. These characteristics make such sources useful for fiber optic systems and optical coherence tomography . 5. Some examples include optical coherence tomography , white light interferometry, optical sensing and fibre optic gyroscopes. 6. Other gastroscopic modalities such as optical coherence tomography are being tested investigationally for similar applications. 7. Medical applications include imaging of the retina, where it has been combined with optical coherence tomography . 8. Optical coherence tomography can be used for more detailed study of retinal nerve fiber layer thickness.9. Optical coherence tomography ( OCT ) represents a powerful clinical tool for monitoring retinal physiology in patients.10. He has been active in the development of optical coherence tomography and its application to urologic imaging.
