    3. Automated macular pathology diagnosis in retinal OCT images using multi-scale spatial pyramid and local binary patterns in texture and shape encoding

      Automated macular pathology diagnosis in retinal OCT images using multi-scale spatial pyramid and local binary patterns in texture and shape encoding
      We address a novel problem domain in the analysis of optical coherence tomography (OCT) images: the diagnosis of multiple macular pathologies in retinal OCT images. The goal is to identify the presence of normal macula and each of three types of macular pathologies, namely, macular edema, macular hole, and age-related macular degeneration, in the OCT slice centered at the fovea. We use a machine learning approach based on global image ...

    4. Aligning Scan Acquisition Circles in Optical Coherence Tomography Images of The Retinal Nerve Fibre Layer

      Aligning Scan Acquisition Circles in Optical Coherence Tomography Images of The Retinal Nerve Fibre Layer
      Optical coherence tomography (OCT) is widely used in the assessment of retinal nerve fibre layer thickness (RNFLT) in glaucoma. Images are typically acquired with a circular scan around the optic nerve head. Accurate registration of OCT scans is essential for measurement reproducibility and longitudinal examination. This study developed and evaluated a special image registration algorithm to align the location of the OCT scan circles to the vessel features in the ...

    6. Blood Vessel Segmentation With Three-Dimensional Spectral Domain Optical Coherence Tomography

      Blood Vessel Segmentation With Three-Dimensional Spectral Domain Optical Coherence Tomography
      In the context of the early detection and monitoring of eye diseases, such as glaucoma and diabetic retinopathy, the use of optical coherence tomography presents the difficulty, with respect to blood vessel segmentation, of weak visibility of vessel pattern in the OCT fundus image. To address this problem, a boosting learning approach uses three-dimensional (3D) information to effect automated segmentation of retinal blood vessels. The automated blood vessel segmentation technique ...

    7. Optic Nerve: Optical Coherence Tomography (Book Chapter)

      Optic Nerve: Optical Coherence Tomography (Book Chapter)
      The Stratus OCT (Carl Zeiss Meditec, Inc., Dublin, CA) is the predominant time-domain OCT in clinical use at the time of this writing. A variety of scan patterns (radial or circular) can be acquired with this device to image the area of interest. The Fast Optic Disc pattern is used to analyze the optic nerve head. The Fast Optic Disc pattern consists of six evenly spaced radial lines centered on ...

    8. Establishing Compatibility Between Two-And Three Dimensional Optical Coherence Tomography Scans (Wo 2010/017356)

      Establishing Compatibility Between Two-And Three Dimensional Optical Coherence Tomography Scans (Wo 2010/017356)
      Advances in optical coherence tomography (OCT) have prompted a transition from time domain OCT, providing 2D OCT images, to spectral domain OCT, which has a 3D imaging capability. Yet conventional technology offers little toward the goal of inter-device compatibility between extant 2D OCT images and newer 3D OCT images for the same or comparable subjects, as in the context of ongoing monitoring the quantitative status of a patient's eyes ...

      Feature Of The Week 1/24/10: Detection of Macular Ganglion Cell Loss in Glaucoma by Fourier-Domain Optical Coherence Tomography
      Feature Of The Week 1/24/10: David Huang was one of the co-inventors of Optical Coherence Tomography and has continued to do pioneering research in OCT from his early days doing PhD work at the Massachusetts Institute of Technology to his current position as a professor of ophthalmology at the Keck School of Medicine at the University of Southern California. A topic recently studied by Dr. Huang and his ...
