      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 ...

      Comparison Between Spectral-Domain and Swept-Source Optical Coherence Tomography Angiographic Imaging of Choroidal Neovascularization
      Purpose : The purpose of this study was to compare imaging of choroidal neovascularization (CNV) using swept-source (SS) and spectral-domain (SD) optical coherence tomography angiography (OCTA). Methods : Optical coherence tomography angiography was performed using a 100-kHz SS-OCT instrument and a 68-kHz SD-OCTA instrument (Carl Zeiss Meditec, Inc.). Both 3 3- and 6 6-mm 2 scans were obtained on both instruments. The 3 3-mm 2 SS-OCTA scans consisted of 300 A-scans per ...

      Deep Learning Is Effective for Classifying Normal versus Age-Related Macular Degeneration Optical Coherence Tomography Images
      Purpose The advent of electronic medical records (EMRs) with large electronic imaging databases along with advances in deep neural networks with machine learning has provided a unique opportunity to achieve milestones in automated image analysis. Optical coherence tomography (OCT) is the most common imaging modality in ophthalmology and represents a dense and rich data set when combined with labels derived from the EMR. We sought to determine whether deep learning ...

      Ultralong-range optical coherence tomography-based angiography by akinetic swept source
      Most of current OCT-based angiography suffers from small FOV with short imaging range. Here we implement an ultralong-range OCT system for vascular imaging based on an akinetic swept source. This swept-source OCT (SS-OCT) system enables us to achieve up to 46 mm long imaging range with unprecedented roll-off performance. To compare with traditional spectral domain OCT (SD-OCT) system, we demonstrated the vascular imaging of the entire mice brain with wide ...

      Non-contact rapid optical coherence elastography by high-speed 4D imaging of elastic waves
      Shear wave OCE (SW-OCE) uses an OCT system to track propagating mechanical waves, providing the information needed to map the elasticity of the target sample. In this study we demonstrate high speed, 4D imaging to capture transient mechanical wave propagation. Using a high-speed Fourier domain mode-locked (FDML) swept-source OCT (SS-OCT) system operating at ~1.62 MHz A-line rate, the equivalent volume rate of mechanical wave imaging is 16 kvps (kilo-volumes ...

      Optical coherence tomography based angiography [Invited]
      Optical coherence tomography (OCT)-based angiography (OCTA) providesin vivo, three-dimensional vascular information by the use of flowing red blood cells as intrinsic contrast agents, enabling the visualization of functional vessel networks within microcirculatory tissue beds non-invasively, without a need of dye injection. Because of these attributes, OCTA has been rapidly translated to clinical ophthalmology within a short period of time in the development. Various OCTA algorithms have been developed to ...

      Acoustic micro-tapping for non-contact 4D imaging of tissue elasticity
      Elastography plays a key role in characterizing soft media such as biological tissue. Although this technology has found widespread use in both clinical diagnostics and basic science research, nearly all methods require direct physical contact with the object of interest and can even be invasive. For a number of applications, such as diagnostic measurements on the anterior segment of the eye, physical contact is not desired and may even be ...
