    4. Dual-Angle Protocol for Doppler Optical Coherence Tomography to Improve Retinal Blood Flow Measurement

      Dual-Angle Protocol for Doppler Optical Coherence Tomography to Improve Retinal Blood Flow Measurement

      Purpose: To compare the performance of two different multiple-scan protocols for total retinal blood flow (TRBF) measurement using Doppler optical coherence tomography (OCT). Methods: In the “single-angle” protocol, five Doppler scans were acquired at a single beam angle. In the “dual-angle” protocol, three scans were obtained with the OCT beam passing through the supranasal portion of the pupil and three through the infranasal portion. The data were analyzed using a custom software termed “Doppler OCT of Retinal Circulation” (DOCTORC) to generate TRBF measurements. In DOCTORC, the measurement of a vein was considered unreliable if the Doppler angle was less than ...

    7. Method and apparatus for quantitative imaging of blood perfusion in living tissue

      Method and apparatus for quantitative imaging of blood perfusion in living tissue

      Embodiments provide methods and systems for quantitative imaging of blood perfusion in living tissue. A method provides for obtaining an optical microangiography (OMAG) image of a sample, wherein the image has an OMAG background sample; digitally reconstructing a homogeneous ideal static background tissue; replacing the OMAG background sample with the digitally reconstructed homogeneous ideal static background tissue; correlating two or more neighboring A-lines with the digitally reconstructed homogeneous ideal static background tissue; and measuring a phase difference between the two or more neighboring A-lines to quantify blood perfusion in the sample. Methods using digital reconstruction to reduce random phase noise ...

    8. Oregon Health & Science University Receives NIH Grant for Ossicle Vibration Measurements in Conductive Hearing Loss.

      Oregon Health & Science University Receives NIH Grant for Ossicle Vibration Measurements in Conductive Hearing Loss.

      Oregon Health & Science University Receives a 2014 NIH Grant for $427,225 for Ossicle Vibration Measurements in Conductive Hearing Loss. The principle investigator is Steven Jacques. The program began in 2013 and ends in 2017. Below is a summary of hte propose work. The proposal develops a hand-held otoscope that uses optical coherence tomography (OCT) to image the tympanic membrane and ossicles behind an intact tympanic membrane. The system is based on spectral Fourier-domain OCT and can measure vibrations of the ossicles (malleus, incus, stapes) of the middle ear on the scale of nm to ¿m amplitude. In Aim 1 ...

    9. Oregon Health & Science University Receives NIH grant to study Dynamic Changes in the Chick Developing Heard in Response to Altered Hemodyanmics

      Oregon Health & Science University Receives NIH grant to study Dynamic Changes in the Chick Developing Heard in Response to Altered Hemodyanmics

      Oregon Health & Science University received at 2014 NIH grant for $404,161 to study Dynamic Changes in the Chick Developing Heard in Response to Altered Hemodyanmics. The principal investigator is Sandra Rugonyi. The program began in 2008 and ends in 2015. Below is a summary of the proposed work. About 1% newborn babies have congenital heart disease (CHD), the leading cause of death among children. The majority of CHD cases are believed not to have a genetic cause. Other factors, such as abnormal blood flow during embryonic and fetal stages can lead to heart malformations and thus CHD through poorly ...

  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.
