4. Evaluation of complex conjugate artifact removal methods used in spectrometer-based Fourier-domain optical coherence tomography systems - a comparative study

   Explore Article SPIE Digital Library (Feb 19 2010)

   We evaluated several, previously published, complex conjugate artifact removal methods and algorithms that have been proposed for Fourier domain optical coherence tomography (Fd-OCT). To ensure comparable conditions, only one OCT system was used, but with modified data acquisition schemes, depending on the requirements of each method/algorithm. This limited our evaluation to single spectrometer based Fd-OCT approaches. The suppression ratio of complex conjugate artifact images using a paperboard is assessed for ... (Read Full Article)

5. Volumetric microvascular imaging of human retina using optical coherence tomography with a novel motion contrast technique

   Explore Article opticsinfobase.org (Nov 19 2009) Ophthalmology

   Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated with vasculature. Histogrambased noise analysis of the motion contrast images was used to reduce the motion noise created by transverse eye motion. En face summation images created from the 3D motion contrast data are presented with ... (Read Full Article)

   Explore Article Archives of Ophthalmology (Jul 12 2009) Ophthalmology

   Objective  To determine if panretinal photocoagulation (PRP) alters retinal nerve fiber layer (RNFL) thickness and optic nerve appearance. Methods  Patients with diabetes who did and did not undergo PRP and nondiabetic control subjects were enrolled in a prospective study. Participants underwent optical coherence tomography of the peripapillary retina and optic nerve. Stereoscopic optic nerve photographs were graded in a masked fashion. Results  Ninety-four eyes of 48 healthy individuals, 89 eyes ... (Read Full Article)

8. Optical coherence tomography and Raman spectroscopy of the ex-vivo retina

   Explore Article www3.interscience.wiley.com (Jun 30 2009) Ophthalmology

   Imaging the structure and correlating it with the biochemical content of the retina holds promise for fundamental research and for clinical applications. Optical coherence tomography (OCT) is commonly used to image the 3D structure of the retina and while the added functionality of biochemical analysis afforded by Raman scattering could provide critical molecular signatures for clinicians and researchers, there are many technical challenges to combine these imaging modalities. We describe ... (Read Full Article)

    Explore Article Home: SPIE.org (Apr 6 2009) Ophthalmology

    A device combining optical coherence tomography and adaptive optics can capture micron-scale 3D pictures of the retina. Viewing the retina through the eye's cornea and crystalline lens dates back to the time of Helmholtz, inventor of the ophthalmoscope. Ophthalmoscopes have advanced substantially since then and are now an indispensable non-invasive tool for diagnosis and treatment monitoring. While there are three principal types—conventional ophthalmoscopes, confocal scanning laser ophthalmoscopes (cSLOs), and optical ... (Read Full Article)
