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. It is effectively ‘optical ultrasound’, imaging reflections from within tissue to provide cross-sectional images.

13 aug 2008 following its original description by huang and workers in 1991, optical coherence tomography (oct) has steadily evolved into an integral.
Spectral domain optical coherence tomography (sd-oct) is the second generation of optical coherence tomography. In comparison to the first generation time domain optical coherence tomography (td- oct), sd-oct is superior in terms of its capturing speed, signal to noise ratio, and sensitivity.
Background and objective: to compare images of geographic atrophy (ga) obtained using spectral domain optical coherence tomography (sd-oct) with images obtained using fundus autofluorescence (faf). Patients and methods: five eyes from patients with dry amd were imaged using sd-oct and faf, and the size and shape of the ga were compared. Results: ga appears bright on sd-oct compared with the surrounding areas with an intact retinal pigment epithelium because of increased.

Abstract this paper reviews the current state of research in spectral domain optical coherence tomography (sdoct). Sdoct is an interferometric technique that provides depth-resolved tissue structure information encoded in the magnitude and delay of the back-scattered light by spectral analysis of the interference fringe pattern.
Purpose: spectral domain optical coherence tomography (sd-oct) allows cross-sectional visualization of retinal structures in vivo. Here, the authors report the efficacy of a commercially available sd-oct device to study mouse models of retinal degeneration. Methods: c57bl/6 and balb/c wild-type mice and three different mouse models of hereditary retinal degeneration (rho (-/-), rd1, rpe65 (-/-)) were investigated using confocal scanning laser ophthalmoscopy (cslo) for en face visualization.

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 inferometry to create a cross-sectional map of the retina that is accurate to within at least 10-15 microns. Oct was first introduced in 1991 and has found many uses outside of ophthalmology, where it has been used to image certain non-transparent tissues.
In choroidal tumors, traditional time-domain and spectral-domain optical coherence tomography (sd-oct) are most useful for visualizing secondary changes to the retina and retinal pigment epithelium (rpe). 21 in choroidal hemangiomas, oct can be used to demonstrate macular edema, epiretinal membranes, and subretinal fluid (fig.
Spectral domain optical coherence tomography (sd-oct) as one kind of oct has become a very important biological imaging modality, especially in ophthalmology, because of its advantages of high resolution, fast imaging speed, and high signal-to-noise ratio (snr) [1,2,3]. Imaging speed and imaging depth are two significant performance indications.
A recent advance in oct technology, spectral-domain oct (sd-oct), has significantly increased scanning speeds (more than 100 fold in some cases) and has been touted as a dramatic advance in retinal imaging.
Optical coherence tomography (oct), first described in 1991, is a noncontact, noninvasive imaging technique that can reveal layers of the retina by looking at the interference patterns of reflected laser light.
It is the current gold standard for posterior segment retinal tomography. Since 2004, higher-resolution spectral-domain oct (sd oct) has entered clinical practice.
