    2. Quantifying the vascular response to ischemia with speckle variance optical coherence tomography

      Quantifying the vascular response to ischemia with speckle variance optical coherence tomography
      Longitudinal monitoring techniques for preclinical models of vascular remodeling are critical to the development of new therapies for pathological conditions such as ischemia and cancer. In models of skeletal muscle ischemia in particular, there is a lack of quantitative, non-invasive and long term assessment of vessel morphology. Here, we have applied speckle variance optical coherence tomography (OCT) methods to quantitatively assess vascular remodeling and growth in a mouse model of ...

      Feature Of The Week 10/06/13: Vanderbilt University Investigates Gold Nanorod Contrast Agents for Photothermal OCT
      Photothermal OCT (PTOCT) is a functional extension of OCT that images oscillations in optical path length due to heat release from an absorber. These oscillations are induced by an amplitude-modulated photothermal laser that is incident on the sample. After photon absorption, heat is released into the microenvironment, which alters the local geometric path length and index of refraction. Phase-sensitive PTOCT is then used to map these index of refraction oscillations ...

    5. Cross-Sectional Tracking of Particle Motion in Evaporating Drops: Flow Fields and Interfacial Accumulation

      Cross-Sectional Tracking of Particle Motion in Evaporating Drops: Flow Fields and Interfacial Accumulation
      The lack of an effective technique for three-dimensional flow visualization has limited the experimental exploration of the coffee ring effect to the two dimensional, top-down viewpoint. In this report, high-speed, cross-sectional imaging of the flow fields was obtained by using optical coherence tomography to track particle motion in an evaporating colloidal water drop. This approach enables z-dimensional mapping of primary and secondary flow fields and changes in these fields over ...
