      Eckhaus Instability in the Fourier-Domain Mode Locked Fiber Laser Cavity
      High frequency fluctuation in the optical signal generated in Fourier-Domain Mode Locked fiber laser (FDML-FL), which is the major problem and degrades the laser performance, is not yet fully analyzed or studied. The basic theory which is causing this high frequency fluctuation is required to clearly understand its dynamics and to control it for various applications. In this letter, by analyzing the signal and system dynamics of FDML-FL, we theoretically ...

      Optical coherence tomography imaging of cranial meninges post brain injury in vivo
      We report a new application of optical coherence tomography (OCT) to investigate the cranial meninges in an animal model of brain injury in vivo. The injury is induced in a mouse due to skull thinning, in which the repeated and excessive drilling exerts mechanical stress on the mouse brain through the skull, resulting in acute and mild brain injury. Transcranial OCT imaging reveals an interesting virtual space between the cranial ...

      The effect of age on the response of retinal capillary filling to changes in intraocular pressure measured by optical coherence tomography angiography
      Purpose To compare the effect of elevated intraocular pressure (IOP) on retinal capillary filling in elderly vs adult rats using optical coherence tomography angiography (OCTA). Methods The IOP of elderly (24-month-old, N = 12) and adult (68 month-old, N = 10) Brown Norway rats was elevated in 10 mmHg increments from 10 to 100 mmHg. At each IOP level, 3D OCT data were captured using an optical microangiography (OMAG) scanning protocol and ...

      Optical coherence tomography angiography: A comprehensive review of current methods and clinical applications
      OCT has revolutionized the practice of ophthalmology over the past 1020 years. Advances in OCT technology have allowed for the creation of novel OCT-based methods. OCT-Angiography (OCTA) is one such method that has rapidly gained clinical acceptance since it was approved by the FDA in late 2016. OCTA images are based on the variable backscattering of light from the vascular and neurosensory tissue in the retina. Since the intensity and ...

      Deep-learning based, automated segmentation of macular edema in optical coherence tomography
      Evaluation of clinical images is essential for diagnosis in many specialties. Therefore the development of computer vision algorithms to help analyze biomedical images will be important. In ophthalmology, optical coherence tomography (OCT) is critical for managing retinal conditions. We developed a convolutional neural network (CNN) that detects intraretinal fluid (IRF) on OCT in a manner indistinguishable from clinicians. Using 1,289 OCT images, the CNN segmented images with a 0 ...

    9. Automatic motion correction for in vivo human skin optical coherence tomography angiography through combined rigid and nonrigid registration

      Automatic motion correction for in vivo human skin optical coherence tomography angiography through combined rigid and nonrigid registration
      When using optical coherence tomography angiography (OCTA), the development of artifacts due to involuntary movements can severely compromise the visualization and subsequent quantitation of tissue microvasculatures. To correct such an occurrence, we propose a motion compensation method to eliminate artifacts from human skin OCTA by means of step-by-step rigid affine registration, rigid subpixel registration, and nonrigid B-spline registration. To accommodate this remedial process, OCTA is conducted using two matching all-depth ...

      Optical coherence tomography angiography-based capillary velocimetry
      Challenge persists in the field of optical coherence tomography (OCT) when it is required to quantify capillary blood flow within tissue beds in vivo . We propose a useful approach to statistically estimate the mean capillary flow velocity using a model-based statistical method of eigendecomposition (ED) analysis of the complex OCT signals obtained with the OCT angiography (OCTA) scanning protocol. ED-based analysis is achieved by the covariance matrix of the ensemble ...

      Spontaneous Coronary Artery Dissection: Insights From Histology and Optical Coherence Tomography
      Spontaneous coronary artery dissection (SCAD) is a well-known but infrequent cause of acute coronary syndrome (ACS), and often goes unrecognized. Although management of SCAD is, at times, controversial, when a patient presents with ACS, percutaneous coronary intervention (PCI) is frequently necessary. We present a patient with ST-segment elevation myocardial infarction (STEMI) with SCAD that illustrates two important points: use of intracoronary optical coherence tomography to guide PCI, and histologic assessment ...

      Robust numerical phase stabilization for long-range swept-source optical coherence tomography
      A novel phase stabilization technique is demonstrated with significant improvement in the phase stability of a micro-electromechanical (MEMS) vertical cavity surface-emitting laser (VCSEL) based swept-source optical coherence tomography (SS-OCT) system. Without any requirements of hardware modifications, the new fully numerical phase stabilization technique features high tolerance to acquisition jitter, and significantly reduced budget in computational effort. We demonstrate that when measured with biological tissue, this technique enables a phase sensitivity ...

      Purpose: To compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system and both with intraocular pressure (IOP) following trabeculectomy surgery. Materials and Methods: A novel AS-OCT grading system based on bleb size and internal reflectivity was developed. An imaging center was tasked with masked grading of AS-OCT images acquired by multiple surgical sites at postoperative week (POW) 2, postoperative month (POM ...
