OCT can be used to capture functional images of blood flow, a technique known as optical coherence tomography angiography (OCT-A). SV-OCT is one method for OCT-A that uses the variance of consecutively acquired images to detect flow at the micron scale. SV-OCT can be used to measure the microvasculature of tissue.
Endoscopic optical coherence tomography, also intravascular optical coherence tomography is a catheter-based imaging application of optical coherence tomography (OCT). [1] It is capable of acquiring high-resolution images from inside a blood vessel using optical fibers and laser technology.
One approach to decreasing the influence of movement on signal detection is to shorten the scanning time. A short scan time prevents too much patient movement during signal acquisition. With the development of Fourier-domain OCT, spectral-domain OCT, and swept source signal acquisition time was greatly improved making OCTA possible. [40]
Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
OCT Biomicroscopy is the use of optical coherence tomography (OCT) in place of slit lamp biomicroscopy to examine the transparent axial tissues of the eye. [1] Traditionally, ophthalmic biomicroscopy has been completed with a slit lamp biomicroscope that uses slit beam illumination and an optical microscope to enable stereoscopic, magnified, cross-sectional views of transparent tissues in the ...
Carl Zeiss Meditec AG is a multinational medical technology company and subsidiary of Carl Zeiss AG. It manufactures tools for eye examinations and medical lasers as well as solutions for neurosurgery, dentistry, gynecology and oncology. Among its products are the most common tools used by ophthalmologists and optometrists.
The first optically feasible stereomicroscope was invented in 1892 and became commercially available in 1896, produced by Zeiss AG in Jena, Germany. [2] 1896 Greenough Stereo Microscope by Carl Zeiss Jena. American zoologist Horatio Saltonstall Greenough grew up in the elite of Boston, Massachusetts, the son of the famous sculptor Horatio ...
The design of photographic lenses for use in still or cine cameras is intended to produce a lens that yields the most acceptable rendition of the subject being photographed within a range of constraints that include cost, weight and materials.
