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.
Ocular OCT retinal thickness map, right eye Time-domain OCT of the macular area of a retina at 800 nm, axial resolution 3 μm Spectral-domain OCT macula cross-section scan. Optical coherence tomography (OCT) is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope.
Aroun 2008-2009, the advent of rapid sweep source lasers allowed for the development of intravascular Fourier-Domain OCT (FD-OCT). [ 9 ] [ 10 ] This enabled for the first-time rapid acquisitions of a long coronary segment in a couple of seconds, allowing non occlusive brief contrast injections to clear the arterial lumen from blood.
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] OCTA scan time is now around three seconds, however, saccadic eye movement still causes a low signal-to-noise ratio.
