    2. Optical Coherence Tomography in Coronary Artery Disease: Toward Sub cellular Imaging

      Optical Coherence Tomography in Coronary Artery  Disease: Toward Sub cellular Imaging

      Intracoronary optical coherence tomography (OCT) is an interferometric imaging technology that uses near-infrared light to provide cross-sectional images with an axial resolution of 10 μm and a transverse of 20-40 μm in vivo. The imaging capabilities of OCT have enabled visualization of important features of coronary plaque, including thrombus, macrophage, neovascularization, stent implantation and stent strut coverage, which have provided new insights for better understanding of this disease. Frequency domain (FD)-OCT is secondgeneration form of OCT that is able to acquire OCT images at a much higher frame. The high-speed imaging capabilities of FD-OCT have made intravascular OCT practical ...

    5. Cross-validation of serial optical coherence scanning and diffusion tensor imaging: A study on neural fiber maps in human medulla oblongata

      Cross-validation of serial optical coherence scanning and diffusion tensor imaging: A study on neural fiber maps in human medulla oblongata

      We established a strategy to perform cross-validation of serial optical coherence scanner imaging (SOCS) and diffusion tensor imaging (DTI) on a postmortem human medulla. Following DTI, the sample was serially scanned by SOCS, which integrates a vibratome slicer and a multi-contrast optical coherence tomography rig for large-scale three-dimensional imaging at microscopic resolution. The DTI dataset was registered to the SOCS space. An average correlation coefficient of 0.9 was found between the co-registered fiber maps constructed by fractional anisotropy and retardance contrasts. Pixelwise comparison of fiber orientations demonstrated good agreement between the DTI and SOCS measures. Details of the comparison ...

    6. Choroidal Haller's and Sattler's Layer Thickness Measurement Using 3-Dimensional 1060-nm Optical Coherence Tomography

      Choroidal Haller's and Sattler's Layer Thickness Measurement Using 3-Dimensional 1060-nm Optical Coherence Tomography

      Objectives To examine the feasibility of automatically segmented choroidal vessels in three-dimensional (3D) 1060-nmOCT by testing repeatability in healthy and AMD eyes and by mapping Haller's and Sattler's layer thickness in healthy eyes Methods Fifty-five eyes (from 45 healthy subjects and 10 with non-neovascular age-related macular degeneration (AMD) subjects) were imaged by 3D-1060-nmOCT over a 36°x36° field of view. Haller's and Sattler's layer were automatically segmented, mapped and averaged across the Early Treatment Diabetic Retinopathy Study grid. For ten AMD eyes and ten healthy eyes, imaging was repeated within the same session and on another ...
