      Akinetic swept-source optical coherence tomography based on a pulse-modulated active mode locking fiber laser for human retinal imaging
      Optical coherence tomography (OCT) is a noninvasive imaging modality that can provide high-resolution, cross-sectional images of tissues. Especially in retinal imaging, OCT has become one of the most valuable imaging tools for diagnosing eye diseases. Considering the scattering and absorption properties of the eye, the 1000-nm OCT system is preferred for retinal imaging. In this study, we describe the use of an akinetic swept-source OCT system based on a pulse-modulated ...

      Comparison of anterior segment optical coherence tomography findings in acanthamoeba keratitis and herpetic epithelial keratitis
      This study is to investigate the characteristic features of Acanthamoeba keratitis (AK) that differentiating it from herpetic epithelial keratitis (HEK) using anterior segment optical coherence tomography (AS-OCT). Medical records of three eyes of each AK and herpetic keratitis who had AS-OCT examination were reviewed in this study. Slit-lamp biomicroscopy and AS-OCT was performed on the initial visit and on every follow-up visits in all patients. In all three AK cases ...

      Deep brain optical coherence tomography angiography in mice: in vivo, noninvasive imaging of hippocampal formation
      The hippocampus is associated with memory and navigation, and the rodent hippocampus provides a useful model system for studying neurophysiology such as neural plasticity. Vascular changes at this site are closely related to brain diseases, such as Alzheimers disease, dementia, and epilepsy. Vascular imaging around the hippocampus in mice may help to further elucidate the mechanisms underlying these diseases. Optical coherence tomography angiography (OCTA) is an emerging technology that can ...

    7. Unfolding displacement measurement method for the aliasing interferometer signal of a wavelength-comb-swept laser

      Unfolding displacement measurement method for the aliasing interferometer signal of a wavelength-comb-swept laser
      We demonstrate an unfolding displacement measurement method to overcome the aliasing problem of wavelength-comb-swept laser (WCSL). Compared to the conventional wavelength-swept laser (WSL), the WCSL exhibits an extended coherence length, owing to the narrowing spectral linewidth of the etalon filter. However, the aliasing interference signal induces an unexpected back-bounced phenomenon during displacement measurement because of the discretely distributed comb-like periodic spectra of the etalon filter. By using the dual-reference interferometry ...

      Comparable outcomes of intravascular ultrasound or optical coherence tomography-assisted percutaneous coronary intervention
      Aim: The use of intravascular ultrasound (IVUS) or Optical coherence tomography (OCT) to guide stent placement in percutaneous coronary intervention (PCI) leads to better clinical outcomes than use of angiography guidance. We hypothesis which image-assisted PCI could lead better clinical outcomes in acute myocardial infarction (MI) patients. Methods: Among 12, 193 patients enrolled the Korean Acute Myocardial Infarction registry, 1,622 patients undergone image-assisted PCI were assigned to the IVUS-assisted ...

      Reproducibility of Bruch's Membrane Opening-minimum Rim Width Measurements with Spectral Domain Optical Coherence Tomography
      Purpose: To evaluate the reproducibility of Bruch's membrane opening-minimum rim width (BMO-MRW) measurements obtained with Spectralis optical coherence tomography (OCT) in normal and glaucoma subjects. Methods: In total, 123 eyes from 123 subjects (65 healthy, 58 glaucoma subjects) were included. BMO-MRW measurements were repeated three times during the same visit using Spectralis OCT. The BMO points and internal limiting membrane were identified with automated software and corrected manually when ...
