Optical Coherence Tomography [PDF]
Optical coherence tomography (OCT) is an optical imaging modality that performs high-resolution, cross-sectional, subsurface tomographic imaging of the microstructure of tissues. The physical principle of OCT is similar to that of B-mode ultrasound imaging, except that it uses infrared light waves rather than acoustic waves.

Ptychographic optical coherence tomography [PDF]
Ptychography is a robust computational imaging technique that can reconstruct complex light fields beyond conventional hardware limits. However, for many wide-field computational imaging techniques, including ptychography, depth sectioning remains a challenge.

Optical Coherence Tomography [PDF]
Case presentation : A 56-year-old man presented to the hospital with chest pain and a non–ST-segment elevation myocardial infarction. Thrombotic plaque rupture in the left anterior descending coronary artery was treated with an everolimus-eluting stent.

Optical Coherence Tomography [PDF]
A technique called optical coherence tomography (OCT) has been developed for noninvasive cross-sectional imaging in biological systems. OCT uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way that is analogous to ultrasonic pulse-echo imaging.

Optical coherence tomography [PDF]
SummaryThe review provides a concise explanation of principles of operation of different optical coherence tomography methods. A comparative analysis of their advantages and disadvantages is presented in relation to specific applications. The review will assist the reader in making an educated choice on the most suitable optical coherence tomography ...

Tracking optical coherence tomography [PDF]
An experimental tracking optical coherence tomography (OCT) system has been clinically tested. The prototype instrument uses a secondary sensing beam and steering mirrors to compensate for eye motion with a closed-loop bandwidth of 1 kHz and tracking accuracy, to within less than the OCT beam diameter.

Optical Coherence Tomography Angiography [PDF]
This issue of the journal RETINA is devoted to the use of optical coherence tomography (OCT) in creation of a new form of angiography, known as OCT angiography. Optical coherence tomography produces depth-resolved evaluation of the reflectance data from tissue.

Optical coherence tomography angiography
Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that obtained with older forms of imaging.

Optical coherency matrix tomography [PDF]
AbstractThe coherence of an optical beam having multiple degrees of freedom (DoFs) is described by a coherency matrixGspanning these DoFs. This optical coherency matrix has not been measured in its entirety to date—even in the simplest case of two binary DoFs whereGis a 4 × 4 matrix.

Panretinal Optical Coherence Tomography
We introduce a new concept of panoramic retinal (panretinal) optical coherence tomography (OCT) imaging system with a 140° field of view (FOV). To achieve this unprecedented FOV, a contact imaging approach was used which enabled faster, more efficient, and quantitative retinal imaging with measurement of axial eye length.
