    2. Big Ideas from Small Businesses: Vision-related research by innovative thinkers - Imaging the eyes of infants

      Big Ideas from Small Businesses: Vision-related research by innovative thinkers  - Imaging the eyes of infants
      In the early 2000s, Eric Buckland quit his job in the telecommunications industry to apply his Ph.D. in optics to life sciences. "In the community of physicians, researchers, and patients, there's a degree of passion that I hadn't seen in the telecommunications space," Buckland explains. He connected with Joseph Izatt, Ph.D., who was working at Duke University on optical coherence tomography (OCT). Similar to the way ...

    3. Systematic transition to a portable spectral domain optical coherence tomography (SD OCT) handheld system for imaging neonates, infants, and children

      Introduction: Optical coherence tomography (OCT) imaging of the retina and optic nerve is often used in the diagnosis of older children and adults. The purpose of this study was to adapt SD OCT technology for clnical use in infants, taking into account the unique optical characteristic of the infant eye, and customizing SD OCT parameters accordingly.

    4. Optimizing Hand-Held Spectral Domain Optical Coherence Tomography Imaging for Neonates, Infants and Children.

      Purpose. To describe age-related considerations and methods to improve hand-held spectral domain optical coherence tomography (HH-SD OCT) imaging of eyes of neonates, infants and children. Methods. Based on calculated optical parameters for neonatal and infant eyes, individualized SD OCT scan parameters were developed for improved imaging in pediatric eyes. Forty-two subjects from 31 weeks post-menstrual age to 1.5 years were imaged with a portable HH-SD OCT system. Images were ...

      Methods, systems and computer program products for characterizing structures based on interferometric phase data
      Structure profiles from optical interferometric data can be identified by obtaining a plurality of broadband interferometric optical profiles of a structure as a function of structure depth in an axial direction. Each of the plurality of interferometric optical profiles include a reference signal propagated through a reference path and a sample signal reflected from a sample reflector in the axial direction. An axial position corresponding to at least a portion ...

    9. Optical coherence imaging systems having a reduced effective linewidth and methods of using the same

      Frequency domain optical coherence imaging systems have an optical source, an optical detector and an optical transmission path between the optical source and the optical detector. The optical transmission path between the optical source and the optical detector reduces an effective linewidth of the imaging system. The optical source may be a broadband source and the optical transmission path may include a periodic optical filter.

      Handheld device detects blindness in infants
      Every year, some 16,000 babies in the U.S. experience loss of vision due to retinopathy of prematurity (RoP), with 400 to 600 becoming legally blind, according to the National Eye Institute. When babies are born prematurely, their retinal blood vessels don't always develop fully, and the abnormal vessels are more prone to leaking and contracting. If that causes the retina to detach, babies can lose some or ...

    12. Piezoelectric scanning mirrors for endoscopic optical coherence tomography

      A novel piezoelectric scanning mirror design for endoscopic optical coherence tomography (OCT) is presented. OCT is an interferometric technique providing microscopic tomographic sectioning of biological samples with mm-range penetration capability in tissue and is suited for integration with endoscopes using fiber-based light delivery to the sample. The piezoelectric scanning mirror was designed to provide wide-range rapid forwarding-looking scanning of the optical beam at the distal end of a compact catheter ...

    1. An historic issue with OCT is that the depth resolution is typically several times better than the lateral resolution...If the layers of imaged tissues happen to be horizontal, then they're well defined in the scan. But to extend the full power of OCT for live imaging of tissues throughout the body, a method for overcoming the tradeoff between lateral resolution and depth of imaging was needed.
