    1. Researchers achieve meter-scale optical coherence tomography for first time

      Researchers achieve meter-scale optical coherence tomography for first time

      An industry-academic collaboration has achieved the first optical coherence tomography (OCT) images of cubic meter volumes. With OCT's ability to provide difficult-to-obtain information on material composition, subsurface structure, coatings, surface roughness and other properties, this advance could open up many new uses for OCT in industry, manufacturing and medicine. The achievement also represents important progress toward developing a high-speed, low-cost OCT system on a single integrated circuit chip. "Our study demonstrates world-record results in cubic meter volume imaging, with at least an order of magnitude larger depth range and volume compared to previous demonstrations of three-dimensional OCT," said James ...

    2. Using light to map the circuitry of the brain

      Using light to map the circuitry of the brain

      Lehigh University bio-engineers are first to explore the use of highly-sensitive, non-invasive optical coherence tomography (OCT) to examine neuron-to-neuron communication in live tissue. Scientific progress has provided a solid understanding of the anatomy of the brain. However, there is still no reliable way to examine neuron to neuron communication, as it happens--a key to understanding the correlation between brain structure and brain function. Chao Zhou , assistant professor of bioengineering at Lehigh University, likens our current brain-mapping ability to a Global Positioning System (GPS) that can help a user locate a city, but cannot offer a street-level view. With current imaging ...

    3. Intravascular imaging identifies some heart attack patients who can forgo stenting

      Intravascular imaging identifies some heart attack patients who can forgo stenting

      Rome, Italy 30 August 2016: More than one quarter of heart attack patients who are normally treated with stents to re-open their blocked arteries might be able to forgo this procedure and receive anti-thrombotic medications only, according to results of a pilot study. Results of the EROSION (Effective Anti-thrombotic Therapy without Stenting: Intravascular OCT-based Management in Plaque Erosion) study, presented in a Hot Line session at ESC Congress 2016, and published simultaneously in the European Heart Journal , suggest "a potentially major change in the treatment of a significant number of patients with acute coronary syndromes (ACS)," said lead investigator Ik-Kyung ...

      Handheld device takes high-resolution images of children's retinas

      Engineers and physicians at Duke University have developed a handheld device capable of capturing images of a retina with cellular resolution. The new probe will allow researchers to gather detailed structural information about the eyes of infants and toddlers for the first time. "Diagnostic tools that examine and image the retina have been well-designed for adults, but are exceedingly difficult to use in infants and young children who can't hold the required position or focus for long enough periods of time," said Cynthia Toth, professor of ophthalmology and biomedical engineering at Duke University. "Before now, it hasn't been ...

    5. Co-invented by OHSU's Dr. David Huang 25 years ago, OCT technology helps stop blindness

      Co-invented by OHSU's Dr. David Huang 25 years ago, OCT technology helps stop blindness

      The Association for Research in Vision and Ophthalmology today published a special anniversary edition in their journal Investigative Ophthalmology & Visual Science with more than 70 articles to commemorate the 25th anniversary of the invention of Optical Coherence Tomography technology, co-invented by Oregon Health & Science University Casey Eye Institute's David Huang, M.D., Ph.D. while Huang was a Ph.D. student with James Fujimoto, Ph.D. at Massachusetts Institute of Technology. OCT is the most commonly used ophthalmic diagnostic technology worldwide, with an estimated 30 million OCT imaging procedures performed every year. "I am pleased to see how well ...

    6. New discovery on how the inner ear works

      New discovery on how the inner ear works

      Researchers have found that the parts of the inner ear that process sounds such as speech and music seem to work differently than other parts of the inner ear. Researchers from Linköping University are part of the team behind the discovery. "This helps us understand the mechanisms that enable us to perceive speech and music. We hope that more knowledge about the capabilities of the ear will lead to better treatments for the hearing impaired," says Anders Fridberger, professor of neuroscience at Linköping University. To perceive speech and music, you must be able to hear low-frequency sound. And ...

    7. UA engineers zero in on early detection of ovarian cancer

      UA engineers zero in on early detection of ovarian cancer

      University of Arizona researcher Jennifer Barton is leading a two-year, $1 million project funded by the National Cancer Institute to identify imaging biomarkers of ovarian cancer, the most deadly gynecological cancer in the United States. This work may enable the first effective screening system for ovarian cancer. "Located deep in the body, with few early symptoms and no effective screening techniques, ovarian cancer has remained stubbornly difficult to understand, much less effectively combat," said Barton, professor of biomedical engineering, electrical and computer engineering, optical sciences, and agricultural and biosystems engineering, and interim director of the UA BIO5 Institute.

      Collaboration aims to reduce, treat vision problems in astronauts

      To reduce and better treat spaceflight-induced visual impairment, University of Houston (UH) optometrists are collaborating on a NASA study that examines ocular changes seen in a number of astronauts. The research, developed by Heidelberg Engineering, uses Spectralis® Optical Coherence Tomography (OCT), which is a technique for obtaining subsurface images of translucent or opaque materials at a resolution equivalent to a low-power microscope. OCT effectively images reflections from within tissue to provide cross-sectional views. This technology is being used to investigate changes in visual acuity, intraocular pressure, the optic nerve and retinal structures in astronauts exposed to long-duration microgravity aboard the ...

      University of Leicester takes delivery of unique eye imaging equipment

      New technology will help scientists study eye disorders in infants, thanks to charitable donations Generous donations from eye charities have allowed the University of Leicester to buy a unique piece of retinal imaging equipment - the only one of its kind in the UK. The handheld retinal scanner will allow new research into eye disorders such as nystagmus, a condition that causes involuntary twitching movements of the eyes. The device is particularly useful for studying the eyes of young children, who often miss out on diagnoses because standard equipment is unsuitable for use with infants. Nystagmus in children is currently poorly ...

    11. Will individuals with Alzheimer's disease benefit from cataract surgery?

      CLEVELAND—A multi-institutional team of researchers, led by the Mandel School of Applied Social Sciences at Case Western Reserve University, will begin a five-year, $2.9 million National Institutes of Health-funded study. They will examine the lives of patients with both cataracts and Alzheimer's disease (AD) to document how restored vision improves everyday life for people with dementia. "This project addresses a major social justice issue in the disparity in vision care of persons diagnosed with Alzheimer's disease," said Grover "Cleve" Gilmore, dean of the Case Western Reserve Mandel School and principal investigator of the study. Gilmore will ...
