Optical Coherence Tomography (OCT) is a non-invasive diagnostic technique that renders an in vivo cross-sectional view of the retina. OCT utilizes a concept known as interferometry to create a cross-sectional map of the retina that is accurate to within at least 10-15 microns.

2019年8月14日 · Optical coherence tomography (OCT) is a non-contact imaging technique which generates cross-sectional images of tissue with high resolution. Therefore it is especially valuable in organs, where traditional microscopic tissue diagnosis by means of biopsy is not available—such as the human eye.

2019年8月14日 · Optical coherence tomography (OCT) is a non-invasive technique for cross-sectional tissue imaging. It typically uses light in the near-infrared spectral range which has a penetration depth of several hundred microns in tissue.

Optical coherence tomography (OCT) is a high-resolution imaging technique with most of its applications in medicine and biology. OCT uses coherent near-infrared light to obtain micrometer-level depth resolved images of biological tissue or other scattering media.

Optical coherence tomography: basic principles. OCT is an optical imaging modality that is used to perform high resolution, cross-sectional imaging of internal microstructures in materials and biological systems by measuring the echo time delay and magnitude of backscattered light.

2024年10月6日 · Optical coherence tomography is a widely used imaging technique for diagnosing and monitoring the progression of many ophthalmic diseases. This technique provides real-time cross-sectional images of ocular tissues, including but not limited to …

OCT measures the subsurface microstructure of biological tissue by discerning light reflected from different depths within the sample. Similar to ultrasound imaging, the signal from a deeper-lying structure has traveled a longer distance and reaches the detector with a delay.

The operational principles of OCT are very simple. Light comes from a light source, and this light travels through a beam splitter, which splits it into two optical paths. One of them travels through a reference mirror, and the other one goes to the tissue that needs to be examined. The irradiance that comes back from the mirror, as well as the ...

Optical coherence tomography (OCT) is a noninvasive, high-resolution optical imaging technology that creates cross-sectional images from interference signals received from an object under investigation and a local reference.

2002年10月23日 · This report presents the principles of OCT and the state of important OCT applications. OCT synthesises cross-sectional images from a series of laterally adjacent depth-scans.
