    2. Longitudinal deep-brain imaging in mouse using visible-light optical coherence tomography through chronic microprism cranial window

      Longitudinal deep-brain imaging in mouse using visible-light optical coherence tomography through chronic microprism cranial window
      We longitudinally imaged both the superficial and deep cortical microvascular networks in brains of healthy mice and in a mouse model of stroke in vivo using visible-light optical coherence tomography (vis-OCT). We surgically implanted a microprism in mouse brains sealed by a chronic cranial window. The microprism enabled vis-OCT to image the entire depth of the mouse cortex. Following microprism implantation, we imaged the mice for 28 days and found ...

    3. Speckle reduction in visible-light optical coherence tomography using scan modulation

      Speckle reduction in visible-light optical coherence tomography using scan modulation
      We present a technique to reduce speckle in visible-light optical coherence tomography (vis-OCT) that preserves fine structural details and is robust against sample motion. Specifically, we locally modulate B-scans orthogonally to their axis of acquisition. Such modulation enables acquisition of uncorrelated speckle patterns from similar anatomical locations, which can be averaged to reduce speckle. To verify the effectiveness of speckle reduction, we performed in-vivo retinal imaging using modulated raster and ...

    4. Designing visible-light optical coherence tomography towards clinics

      Designing visible-light optical coherence tomography towards clinics
      Background: The capabilities of visible-light optical coherence tomography (vis-OCT) in noninvasive anatomical and functional retinal imaging have been demonstrated by multiple groups in both rodents and healthy human subjects. Translating laboratory prototypes to an integrated clinical-environment-friendly system is required to explore the full potential of vis-OCT in disease management. Methods: We developed and optimized a portable vis-OCT system for human retinal imaging in clinical settings. We acquired raster- and circular-scan ...

    6. Group Refractive Index Measurement of Liquids Using Common-Path Swept Source Optical Coherence Tomography

      Group Refractive Index Measurement of Liquids Using Common-Path Swept Source Optical Coherence Tomography
      A fiber-optic based common-path swept source optical coherence tomography for a simple and high-resolution measurement of the group refractive indices of liquids has been investigated. The group refractive index measurement has been based on the optical length change before and after injection of liquid into a transparent glass tube. The gas-cell referenced fiber based common-path swept source optical coherence tomography instrument was utilized to obtain the group refractive indices of ...

    9. Feature Of The Week 5/26/2013: University of Texas at Austin Investigates Dual-Wavelength Photothermal OCT for Imaging Microvasculature Blood Oxygen Saturation

      Feature Of The Week 5/26/2013: University of Texas at Austin Investigates Dual-Wavelength Photothermal OCT for Imaging Microvasculature Blood Oxygen Saturation
      A swept-source dual-wavelength photothermal optical coherence tomography (DWP-OCT) is demonstrated for imaging and measurement of microvasculature oxygen saturation (SO2). DWP-OCT is capable of recording three-dimensional images of tissue and depth-resolved phase variation in response to photothermal excitations in two different wavelengths (770 and 800 nm). Two phantom microvessels with different inner-diameter size (50 and 300 m) were constructed, porcine blood with various SO2 levels were prepared for the experiment. Phantom ...

    10. Dual-wavelength photothermal optical coherence tomography for imaging microvasculature blood oxygen saturation

      Dual-wavelength photothermal optical coherence tomography for imaging microvasculature blood oxygen saturation
      A swept-source dual-wavelength photothermal (DWP) optical coherence tomography (OCT) system is demonstrated for quantitative imaging of microvasculature oxygen saturation. DWP-OCT is capable of recording three-dimensional images of tissue and depth-resolved phase variation in response to photothermal excitation. A 1,064-nm OCT probe and 770-nm and 800-nm photothermal excitation beams are combined in a single-mode optical fiber to measure microvasculature hemoglobin oxygen saturation ( SO 2 ) levels in phantom blood vessels with ...
