    2. Two dimensional vibrations of the guinea pig apex organ of Corti measured in vivo using phase sensitive Fourier domain optical coherence tomography

      Two dimensional vibrations of the guinea pig apex organ of Corti measured in vivo using phase sensitive Fourier domain optical coherence tomography

      In this study, we measure the in vivo apical-turn vibrations of the guinea pig organ of Corti in both axial and radial directions using phase-sensitive Fourier domain optical coherence tomography. The apical turn in guinea pig cochlea has best frequencies around 100 – 500 Hz which are relevant for human speech. Prior measurements of vibrations in the guinea pig apex involved opening the otic capsule, which has been questioned on the basis of the resulting changes to cochlear hydrodynamics. Here this limitation is overcome by measuring the vibrations through bone without opening the otic capsule. Furthermore, we have significantly reduced the ...

    4. OCT Vitrectomy Probe

      OCT Vitrectomy Probe

      Disclosed herein is a vitrectomy probe, comprising a beam steering system configured to receive a light beam from a sample fiber of an optical coherence tomography instrument; a fundus illumination system configured to receive a beam of white light from a white light source via a multimode fiber; a dichroic mirror; and a beam delivery system configured to illuminate the retina of a subject.

      OHSU Receives a NIH Grant for Functional Optical Coherence Tomography-Derived Biomarkers for Diabetic Retinopathy

      Oregon Health & Science University Receives a 2014 NIH Grant for $1,1036,724 for Functional Optical Coherence Tomography-Derived Biomarkers for Diabetic Retinopathy. The principal investigator is Yali Jia. The program geban in 2014 and ends in 2017. Below is a summary of the proposed work. Diabetic retinopathy (DR), associated with long-term diabetes mellitus, is a leading cause of blindness in the US. Structural optical coherence tomography (OCT) has become the standard method for evaluating diabetic macular edema; however, fluorescein angiography (FA), which requires an invasive intravenous dye injection, is still needed to assess capillary dropout and confirm neovascularization. Recently, we ...

    6. Clinical Guide to Angio-OCT (Non Invasive, Dyeless OCT Angiography) (Textbook)

      Clinical Guide to Angio-OCT (Non Invasive, Dyeless OCT Angiography)  (Textbook)

      The book discusses the clinical possibilities of Angio-OCT. Most imaging in the book (77 figures in Chapters 5, 7.1 and 10) has been performed with XR-Avanti Optovue SD-OCT device using SSADA algorithm. A few figures in chapters 3, 7.2 and 8 have been performed with a swept source OCT prototype using SSADA algorithm. Another technique is described in chapter 11, using ultrahigh speed, SS-OCT and its applications to optical coherence tomography-angiography (OCTA). Key Features Angio-OCT (Dyeless OCT Angiography) is a new TECHNOLOGY that gives already useful results, that can be applied to day-to-day clinical ophthalmology. Several different OCT ...

  2. About Oregon Health & Science University

    Oregon Health & Science University

    Oregon Health & Science University (OHSU) is a public university in Oregon with a main campus, including three hospitals, in Portland and a smaller campus in Hillsboro. It was formed in 1974 as the University of Oregon Health Sciences Center, combining state dentistry, medicine, and nursing programs into a single center. It was renamed Oregon Health Sciences University in 1981 and took its current name in 2001, as part of a merger with the Oregon Graduate Institute of Science and Technology (OGI) in Hillsboro. In addition, the university has several partnership programs including a joint PharmD Pharmacy program with Oregon State University.
