    1. Diagnostic accuracy of optical coherence tomography angiography for choroidal neovascularization: a systematic review and meta-analysis

      Diagnostic accuracy of optical coherence tomography angiography for choroidal neovascularization: a systematic review and meta-analysis

      Background Optical coherence tomography angiography (OCTA), an innovative image technique, renders visualization of ocular neovascularization through non-invasive means, which has been applied in recent years. Therefore, the present study was designed to assess the diagnostic value of OCTA in detecting the choroidal neovascularization (CNV). Methods In brief, PubMed, Web of Science and Cochrane Library databases were systematically searched from January 2014 to June 2019. Afterwards, a meta-analysis was performed to determine the pooled diagnostic accuracy in a random-effects model using STATA 15.1 and Meta-Disc 1.4 software. Quality Assessment of diagnostic Accuracy Version 2 was used to evaluate the ...

    2. Granular Hyperreflective Specks By Spectral Domain Optical Coherence Tomography As Signs Of West Nile Virus Infection: The Stardust Sign

      Granular Hyperreflective Specks By Spectral Domain Optical Coherence Tomography As Signs Of West Nile Virus Infection:  The Stardust Sign

      Purpose: To report the retinal findings and evolution of a visually symptomatic case of West Nile virus meningoencephalitis. Methods: Case report. Main outcome measures include serologic testing for West Nile virus as well as longitudinal funduscopic examination, fluorescein angiography, and spectral domain optical coherence tomography. Results: A 47-year-old diabetic man was referred for ophthalmic evaluation after hospitalization and treatment for West Nile meningoencephalitis. The patient presented with decreased vision and black spots in the right eye. Baseline visual acuity was 20/100 in the right eye and 20/40 in the left. Funduscopic examination and fluorescein angiography revealed multiple outer-retinal ...

    4. 4D imaging of embryonic chick hearts by streak-mode Fourier domain optical coherence tomography

      4D imaging of embryonic chick hearts by streak-mode Fourier domain optical coherence tomography

      Recently, we developed the streak-mode Fourier domain optical coherence tomography (OCT) technique in which an area-scan camera is used in a streak-mode to record the OCT spectrum. Here we report the application of this technique to in ovo imaging HH18 embryonic chick hearts with an ultrahigh speed of 1,016,000 axial scans per second. The high-scan rate enables the acquisition of high temporal resolution 2D datasets (1,000 frames per second or 1 ms between frames) and 3D datasets (10 volumes per second), without use of prospective or retrospective gating technique. This marks the first time that the embryonic ...

    5. Doppler streak mode Fourier domain optical coherence tomography

      Doppler streak mode Fourier domain optical coherence tomography

      Doppler Fourier domain optical coherence tomography is able to be used for in vivo blood flow measurement. In conventional methods, the highest velocity that can be measured is limited to the range the phase shift between two successively recorded depth profiles at the same probe-beam location, which cannot exceed (-π, π), otherwise phase wrapping will occur. This phase-wrapping limit is determined by the time interval between two consecutive A-scans. We present a novel approach to shorten the time interval between two consecutive A-scans and thus increase the phase-wrapping limit by using an area scan camera to record the interference spectrum ...

    6. Megahertz streak-mode Fourier domain optical coherence tomography

      Megahertz streak-mode Fourier domain optical coherence tomography
      Here we present an ultrahigh-speed Fourier-domain optical coherence tomography (OCT) that records the OCT spectrum in streak mode with a high-speed area scan camera, which allows higher OCT imaging speed than can be achieved with a line-scan camera. Unlike parallel OCT techniques that also use area scan cameras, the conventional single-mode fiber-based point-scanning mechanism is retained to provide a confocal gate that rejects multiply scattered photons from the sample. When using a 1000 Hz resonant scanner as the streak scanner, 1,016,000 A-scans have been obtained in 1 s. This method's effectiveness has been demonstrated by recording in ...

      Development Of Fourier Domain Optical Coherence Tomography A Dissertation ...

      Fourier domain optical coherence tomography (FD-OCT) is a high-speed, highresolution, and noninvasive imaging technique that can obtain cross-sectional images of light scattering medium, such as biomedical tissues. In this thesis, I report three novel methods in FD-OCT technique including common-path endoscopic FD-OCT, streakmode FD-OCT, and Doppler streak-mode FD-OCT. Finally, I apply the streak mode FDOCT to ultrahigh-speed, noninvasive, live imaging of embryonic chick hearts. An extension of conventional FD-OCT technique is endoscopic FD-OCT, which can access internal organs by utilizing a miniaturized catheter design. However, its image signal suffers from the bending of the endoscopic catheter. To address this problem ...

    8. An approach for megahertz OCT: streak mode Fourier domain optical coherence tomography

      An approach for megahertz OCT: streak mode Fourier domain optical coherence tomography

      We report a technique, which uses an area-scan camera to record the interference spectrum. Traditional point-scanning is remained in this streak-mode FDOCT so that the small aperture of the single-mode fiber functions as a confocal gate and screens multiply scattered photons very well. While the sample beam is scanning the specimen laterally, the interference spectrum is physically scanned on the area scan camera using a streak scanner. Therefore, pixels of the camera are illuminated by the spectrum of OCT signal row by row, corresponding to each A-scan at different lateral position. A unidirectional B-scan of 700 lines is obtained in ...

    9. Ultra-high-resolution full-field optical coherence tomography for imaging of a developing embryo

      Optical coherence tomography (OCT) is a new emerging technique for cross-sectional imaging with high spatial resolution of micrometer scale. It enables in vivo and non-invasive imaging with no need to contact the sample and is widely used in biological and clinic application. In this paper a white-light interference microscope is developed for ultrahigh-resolution full-field optical coherence tomography (Full-Field OCT) to implement 3D imaging of biological tissue. The experimental setup is based on a Linnik-type interferometer illuminated by a tungsten halogen lamp via a bundle of fiber. En-face tomographic images are obtained by demodulation of a combination of interferometric images recorded ...
