    2. Retinal pulse wave velocity measurement using spectral-domain optical coherence tomography

      Retinal pulse wave velocity measurement using spectral-domain optical coherence tomography
      The human eyes provide a natural window for noninvasive measurement of the pulse wave velocity (PWV) of small arteries. By measuring the retinal PWV, the stiffness of small arteries can be assessed, which may better detect early vascular diseases. Therefore, retinal PWV measurement has attracted increasing attention. In this study, a jump-scanning method was proposed for non-invasive measurement of retinal PWV using spectral-domain OCT. The jump-scanning method uses the phase-resolved ...

    6. Visualization of extensive intraplaque neovascularization by optical coherence tomography

      Visualization of extensive intraplaque neovascularization by optical coherence tomography
      Inflammation plays a key role in pathogenesis and progression of atherosclerosis (1) . Advent of novel intravascular imaging tools such as Optical Coherence Tomography (OCT) has led to visualization of coronary atherosclerotic plaque characteristics in vivo that were previously seen only on histology. Herein we discuss a case of extensive neovascularization, a feature that imparts vulnerability to atherosclerotic plaque in the coronary artery, as seen by two- and three-dimensional OCT images ...

    9. Optical Coherence Tomography Angiography Characteristics of Fovea in Residual Subfoveal Perfluorocarbon Liquid Eye

      Optical Coherence Tomography Angiography Characteristics of Fovea in Residual Subfoveal Perfluorocarbon Liquid Eye
      The authors report a case of optical coherence tomography angiography (OCTA) features of retina and choriocapillaris before and after the surgical removal of a subfoveal perfluorocarbon liquid (PFCL) bubble. Before the surgery, the fovea avascular zone (FAZ) of both superficial and deep inner retinal layers (SRL/DRL) dramatically enlarged. However, after the removal, the FAZ continually decreased in both layers, even becoming close to normal in size. The abnormal choriocapillaris ...

    10. Endoscopic optical coherence tomography using compressive sensing

      Endoscopic optical coherence tomography using compressive sensing
      Conventionally endoscopic OCT images are reconstructed by uniform sampling in both axial and transverse direction of the image. To shorten the scanning time and reduce the acquisition data, we propose to sparsely sample the axial scans and use compressive sensing (CS) to reconstruct the full endoscopic OCT image with randomly chosen axial scans that are much less than conventional Nyquist criteria requirement. And we study the ratio of sparse sampling ...

    11. Imaging hemodynamic response after ischemic stroke in mouse cortex using visible-light optical coherence tomography

      Imaging hemodynamic response after ischemic stroke in mouse cortex using visible-light optical coherence tomography
      Visible-light optical coherence tomography (Vis-OCT) is an emerging technology that can image hemodynamic response in microvasculature. Vis-OCT can retrieve blood oxygen saturation (sO 2 ) mapping using intrinsic optical absorption contrast while providing high-resolution anatomical vascular structures at the same time. To improve the accuracy of Vis-OCT oximetry on vessels embedded in highly scattering medium, i.e., brain cortex, we developed and formulated a novel dual-depth sampling and normalization strategy that ...
