      Detection of early stage alzheimer's disease and mild cognitive impairment
      Systems and methods are described herein for determining that a patient has indications mild cognitive impairment (MCI) or early stage Alzheimer's disease (AD). Microperimetry is used to assess the functional integrity of the patient's retina. Optical Coherence Tomography is used to assess the structural integrity of the patient's retina. Reductions in the size and function of the patient's retina indicate that the patient may have MCI ...

      Optical coherence tomography and plaque morphology for revascularization of the superficial femoral artery
      Background: The optical coherence tomography (OCT) catheter, Ocelot (Avinger Inc., Redwood City, CA), has been utilized to cross Trans-Atlantic Inter-Society Consensus Document (TASC) D lesions. Studies have assessed the characteristics of high-risk plaques in the carotid artery, but few, if any data exist evaluating OCT and plaque morphology in the superficial femoral artery (SFA). This study assessed SFA plaque morphology using OCT and lesion crossing success in chronic total occlusions ...

      Temporal dynamics of muscle optical properties during degeneration and regeneration in a canine muscle xenograft model
      We studied time-dependent changes in muscle optical properties during degeneration and regeneration using polarization-sensitive optical coherence tomography (PSOCT). Excised canine muscle transplants in a xenograft mouse model were imaged ex vivo from 3- to 112-day post-transplantation. PSOCT images were quantified to evaluate post-transplantation changes of three optical/structural properties: attenuation, birefringence and fiber alignment. The birefringence and fiber alignment decreased after transplantation until 2030-day and recovered thereafter. The attenuation coefficient ...

      Membrane fouling by clay suspensions during NF-like forward osmosis: Characterization via optical coherence tomography
      The use of a membrane with a relatively loose active layer opened a new paradigm for the application of osmotically driven processes. An effective way of imparting the osmotic pressure difference across the active layer is to employ divalent salts as the draw solute, whose negative effects on the organic fouling have been documented in the literature. This study was targeted on investigating the fouling by clay suspensions when performing ...

      High-resolution 3D tractography of fibrous tissue based on polarization-sensitive optical coherence tomography
      Abstract Fibrous tissues play important roles in many parts of the body. Their highly organized directional structure is essential in achieving their normal biomechanical and physiological functions. Disruption of the typical fiber organization in these tissues is often linked to pathological changes and disease progression. Tractography is a specialized imaging method that can reveal the detailed fiber architecture. Here, we review recent developments in high-resolution optical tractography using Jones matrix ...

      Improve depth of field of optical coherence tomography using finite energy Airy beam
      We report a technique to break the depth of field (DOF) limit in optical coherence tomography (OCT) using a finite energy Airy beam. The Airy beam is generated using a phase mask in a Fourier transform schematic and provides the DOF improvement due to its low diffraction. We compare Airy beam OCT with conventional Gaussian beam OCT using lateral resolution and sensitivity. Experimental data from the polystyrene beads in water ...

      Diurnal variation of choriocapillaris vessel flow density in normal subjects measured using optical coherence tomography angiography
      Background Vessel flow density (VFD) may provide important information regarding perfusion status. Diurnal variation in VFD of choriocapillaris has not been reported in literature. In the index study, optical coherence tomography angiography (OCTA) was used to assess the diurnal variation of the VFD in the choriocapillaris of subjects with no known ocular disease. Methods Fifty eyes with no known ocular disease (25 subjects) were included. OCTA images were acquired using ...

      Three Dimensional Full-Range Dual-Band Fourier Domain Optical Coherence Tomography Accelerated by Graphic Processing Unit
      The authors present a graphic processing unit (GPU) accelerated three-dimensional (3D) full-range dual-band Fourier domain optical coherence tomography (FD-OCT) using a LabVIEW GPU program with GPU-adaptable algorithms. GPU can dramatically reduce the image processing time, but programing on GPU is more complex than that on central processing unit (CPU). This work implements GPU computing interfaced with LabVIEW, using a LabVIEW GPU analysis toolkit, which significantly reduces the programing complexity. The ...

      Parametric imaging of collagen structural changes in human osteoarthritic cartilage using optical polarization tractography
      Collagen degeneration is an important pathological feature of osteoarthritis. The purpose of this study is to investigate whether the polarization-sensitive optical coherence tomography (PSOCT)-based optical polarization tractography (OPT) can be useful in imaging collagen structural changes in human osteoarthritic cartilage samples. OPT eliminated the banding artifacts in conventional PSOCT by calculating the depth-resolved local birefringence and fiber orientation. A close comparison between OPT and PSOCT showed that OPT provided ...

      Heart structural remodeling in a mouse model of Duchenne cardiomyopathy revealed using optical polarization tractography [Invited]
      We investigated the heart structural remodeling in the mdx4cv mouse model of Duchenne cardiomyopathy using optical polarization tractography. Whole heart tractography was obtained in freshly dissected hearts from six mdx4cv mice. Six hearts from C57BL/6J mice were also imaged as the normal control. The mdx4cv hearts were significantly larger than the control hearts and had significantly higher betweensubject variations in myofiber organization. While both strains showed classic cross-helical fiber ...

      Spatial convolution for mirror image suppression in Fourier domain optical coherence tomography
      We developed a spatial convolution approach for mirror image suppression in phase-modulated Fourier domain optical coherence tomography, and demonstrated it in vivo for small animal imaging. Utilizing the correlation among neighboring A-scans, the mirror image suppression process was simplified to a three-parameter convolution. By adjusting the three parameters, we can implement different Fourier domain sideband windows, which is important but complicated in existing approaches. By properly selecting the window size ...

      Nondestructive imaging of fiber structure in articular cartilage using optical polarization tractography
      Collagen fiber orientation plays an important role in determining the structure and function of the articular cartilage. However, there is currently a lack of nondestructive means to image the fiber orientation from the cartilage surface. The purpose of this study is to investigate whether the newly developed optical polarization tractography (OPT) can image fiber structure in articular cartilage. OPT was applied to obtain the depth-dependent fiber orientation in fresh articular ...

    University of Missouri (Mizzou, MU, University of Missouri–Columbia or simply Missouri) is a public research university located in the state of Missouri. In 1839 the university was founded in Columbia, Missouri, as the first public institution of higher education west of the Mississippi River. The largest university in Missouri, MU enrolls 33,805 students in 20 academic colleges in the 2011–12 year. The university is the flagship of the University of Missouri System which maintains campuses in Rolla, Kansas City and St. Louis. MU is one of 34 public universities to be members of the Association of American Universities and the only one in Missouri. There are more than 262,000 MU alumni living worldwide, with almost half continuing to reside in Missouri. The University of Missouri was ranked 90th in the 2012 U.S. News & World Report among the national universities, up four spots from 2011. It is the highest-ranked public school in the state and second overall (tied with Saint Louis University).
