  Purpose: To assess the visualization of choroidal granulomas with swept-source optical coherence tomography angiography (OCTA). Methods: Consecutive patients with granulomatous choroiditis due to tuberculosis, sarcoidosis, or VogtKoyanagiHarada disease underwent baseline OCTA images using a 12 12-mm field of view, and the choroidal slabs were analyzed by two independent examiners who counted the oval areas of flow void. Simultaneously, indocyanine green angiography (ICGA) and enhanced-depth imaging OCT were performed to mark ...

6. Wavelength-encoded multi-channel spectral-domain optical coherence tomography (SD-OCT) for spatiotemporally resolved imaging
  
  Explore IOPscience Apr 7 2020
  
  In conventional SD-OCT, a beam is focused to one spot on the surface of the sample to acquire depth information beneath that spot. Adjacent spots are serially scanned to obtain a tomographic image of the sample; thus, available OCT techniques can take significant time to scan large objects. This paper illustrates an SD-OCT system involving spectral-slicing of a broadband spectrum to enable the simultaneous acquisition from multiple lateral positions of ...

9. Optical coherence tomography diagnostic signs in posterior uveitis
  
  Explore ScienceDirect Sep 14 2019 Ophthalmology
  
  A diagnostic sign refers to a quantifiable biological parameter that is measured and evaluated as an indicator of normal biological, pathogenic, or pharmacologic responses to a therapeutic intervention. When used in translational research discussions, the term itself often alludes to a signs used to accelerate or aid in diagnosis or monitoring and provide insight into personalized medicine. Many new diagnostic signs are being developed that involve imaging technology. Optical coherence ...

  We performed a cross-sectional study to analyze the retinal vasculature in children, adolescent, and young adults with type 1 diabetes using optical coherence tomography angiography (OCTA). Patients underwent funduscopic examination for diabetic retinopathy (DR) screening during an annual visit for the screening of diabetes-related complications which included the evaluation of glycated hemoglobin (HbA1c), microalbuminuria, lipid profile, arterial pressure, and neurological assessment. In addition, OCTA of the retinal vasculature was performed ...

  This paper reports on the characterization of a novel multi-channel Optical Coherence Tomography (MC-OCT) method capable of concurrent scanning at multiple sites along the sample arm length of a low coherence interferometer. For this study, a cascade of two wavelength-based beam splitters is used to split the sample arm beam into three channels, forming three imaging (sensing) units. Channel-specific free-space beam paths are introduced in the sample arm to ensure ...

14. Robust deep learning method for choroidal vessel segmentation on swept source optical coherence tomography images
  
  Explore OSA | OSA Publishing Mar 5 2019 Ophthalmology
  
  Accurate choroidal vessel segmentation with swept-source optical coherence tomography (SS-OCT) images provide unprecedented quantitative analysis towards the understanding of choroid-related diseases. Motivated by the leading segmentation performance in medical images from the use of deep learning methods, in this study, we proposed the adoption of a deep learning method, RefineNet, to segment the choroidal vessels from SS-OCT images. We quantitatively evaluated the RefineNet on 40 SS-OCT images consisting of ~3 ...

  Over the better part of two decades, lessons learned from stent failure have led to technical advances that have resulted in current-generation metallic drug-eluting stents (DES) with very low rates of target lesion failure (TLF) and stent thrombosis 1 . Continued efforts have been directed at achieving iterative improvements in the design of DES to enhance adaptive vascular healing following vascular injury. By promoting early strut coverage with minimal neointimal hyperplasia ...
