    1. METHODS, SYSTEMS AND COMPUTER PROGRAM PRODUCTS FOR PROCESSING IMAGES GENERATED USING FOURIER DOMAIN OPTICAL COHERENCE TOMOGRAPHY (FDOCT) (WO 2008/088868)

      Methods, systems and computer program products for managing frequency domain optical coherence tomography (FDOCT) image resolution. A spectrum used to acquire an image of a subject is calibrated and default dispersion correction parameters are set. Default dispersion management parameters associated with a region of the image of the subject are also set. The image of the subject is acquires after setting the default dispersion correction parameters and the default dispersion ...

    2. Detailed Visualization of the Anterior Segment Using Fourier-Domain Optical Coherence Tomography

      Objective  To study details of the anterior chamber drainage angle using Fourier-domain optical coherence tomography in healthy subjects and patients with angle abnormalities. Methods  A high-speed anterior segment optical coherence tomography prototype was developed using a 1310-nm-wavelength swept light source. Six healthy subjects and 6 patients with glaucoma were imaged in an observational cross-sectional study. Results  Schlemm’s canal and the trabecular meshwork were visualized in all of the patients ...

    3. Development of Fourier Domain Optical Coherence Tomography for Applications in Developmental Biology (Thesis)

      Development of Fourier Domain Optical Coherence Tomography for Applications in Developmental Biology (Thesis)
      Developmental biology is a field in which explorations are made to answer how an organism transforms from a single cell to a complex system made up of trillions of highly organized and highly specified cells. This field, however, is not just for discovery, it is crucial for unlocking factors that lead to diseases, defects, or malformations. The one key ingredient that contributes to the success of studies in developmental biology ...

    4. Methods and systems for reducing complex conjugate ambiguity in interferometric data

      A complex conjugate ambiguity can be resolved in an Optical Coherence Tomography (OCT) interferogram. A reference light signal is propagated along a reference path. A sample light signal is impinged on a sample reflector. The reference light signal is frequency shifted with respect to the sample light signal to thereby separate a positive and a negative displacement of a complex conjugate component of the OCT interferogram.

    5. Extension of spectral domain phase microscopy to three-dimensional nanoscale displacement mapping in cardiomyocytes

      Extension of spectral domain phase microscopy to three-dimensional nanoscale displacement mapping in cardiomyocytes
      Spectral domain phase microscopy (SDPM) is a functional extension of optical coherence tomography (OCT) whose common-path interferometric design enables phase-referenced imaging of dynamic samples. Like OCT, axial resolution in SDPM is determined by the source coherence length, while lateral resolution is limited by diffraction in the microscope optics. Nonetheless, the quantitative phase information SDPM generates is sensitive to sub-Angstrom displacements of scattering structures. Integrative quantitative phase imaging techniques, such as ...

    6. Fast detection and segmentation of drusen in retinal optical coherence tomography images

      Accurate detection-characterization of drusen is an important imaging biomarker of age-related macular degeneration (AMD) progression. We report on the development of an automatic method for detection and segmentation of drusen in retinal images captured via high speed spectral domain coherence tomo ... [Proc. SPIE Int. Soc. Opt. Eng. 6844, 68440D (2008)] published Mon Feb 11, 2008.

    7. Correlation Of Pathologic Features In Spectral Domain Optical Coherence Tomography With Conventional Retinal Studies.

      We delineated pathologic features within three-dimensional spectral domain optical coherence tomography volumes and projected marked sites of pathologic features onto clinically useful two-dimensional localization maps to be overlaid on conventional clinical images.Page: 298DOI: 10.1097/IAE.0b013e3181567798Authors: STOPA, MARCIN MD *+; BOWER, BRADLEY A.

    8. Three-Dimensional Images and Vessel Rendering Using Optical Coherence Tomography

      Optical coherence tomography (OCT) is an emerging technology in dermatology. Translating the principles of ultrasound to use with light waves, OCT captures in vivo images allowing for 3-dimensional reconstruction and Doppler flow measurements. Compared with confocal microscopy, standard OCT has a greater depth of penetration but lower resolution. This places the technology between traditional ultrasound and confocal microscopy in the trade-off between depth penetration and surface resolution (Figure 1). Optical ...

    9. System and method for low coherence broadband quadrature interferometry

      A quadrature broadband interferometry system and method obtains a complete complex interferometric signal instantaneously in both homodyne and heterodyne systems in a simple, compact, and inexpensive setup. This is accomplished by separating interferometric components from non-interferometric components in each of at least two detector signals of an interferometer having a number of N.times.N couplers, scaling the interferometric components, and generating real and imaginary parts of a complex interferometric ...
