    2. Modular deep neural networks for automatic quality control of retinal optical coherence tomography scans

      Modular deep neural networks for automatic quality control of retinal optical coherence tomography scans
      Retinal optical coherence tomography (OCT) with intraretinal layer segmentation is increasingly used not only in ophthalmology but also for neurological diseases such as multiple sclerosis (MS). Signal quality influences segmentation results, and high-quality OCT images are needed for accurate segmentation and quantification of subtle intraretinal layer changes. Among others, OCT image quality depends on the ability to focus, patient compliance and operator skills. Current criteria for OCT quality define acceptable ...

    4. Surface kinematic and depth-resolved analysis of human vocal folds in vivo during phonation using optical coherence tomography

      Surface kinematic and depth-resolved analysis of human vocal folds in vivo during phonation using optical coherence tomography
      Significance: The human vocal fold (VF) oscillates in multiple vectors and consists of distinct layers with varying viscoelastic properties that contribute to the mucosal wave. Office-based and operative laryngeal endoscopy are limited to diagnostic evaluation of the VF epithelial surface only and are restricted to axial-plane characterization of the horizontal mucosal wave. As such, understanding of the biomechanics of human VF motion remains limited. Aim: Optical coherence tomography (OCT) is ...

    5. Vascular characteristics of port wine birthmarks as measured by dynamic optical coherence tomography

      Vascular characteristics of port wine birthmarks as measured by dynamic optical coherence tomography
      Background: Port wine birthmarks (PWB) are congenital capillary malformations. Vessel characteristics, such as diameter and depth, may impact presentation and outcomes. They can be imaged using dynamic optical coherence tomography (D-OCT), a high-resolution, non-invasive imaging method. Purpose: We conducted a cross-sectional observational study to measure in-vivo vascular characteristics as a function of PWB color. Methods: Patients undergoing treatment for PWB were recruited from three sites. PWB were classified by color ...

    6. 1.7-micron Optical Coherence Tomography Angiography for Characterization of Skin Lesions – A Feasibility Study

      1.7-micron Optical Coherence Tomography Angiography for Characterization of Skin Lesions – A Feasibility Study
      Optical coherence tomography (OCT) is a non-invasive diagnostic method that offers real-time visualization of the layered architecture of the skin in vivo. The 1.7-micron OCT system has been applied in cardiology, gynecology and dermatology, demonstrating an improved penetration depth in contrast to conventional 1.3-micron OCT. To further extend the capability, we developed a 1.7-micron OCT/OCT angiography (OCTA) system that allows for a visualization of both morphology ...

    7. The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies

      The APOSTEL 2.0 Recommendations for Reporting Quantitative Optical Coherence Tomography Studies
      Objective: To update the consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results, thus revising the previously published Advised Protocol for OCT Study Terminology and Elements (APOSTEL) recommendations. Methods: To identify studies reporting quantitative OCT results, we performed a PubMed search for the terms "quantitative" and "optical coherence tomography" from 2015 to 2017. Corresponding authors of the identified publications were invited to provide feedback on the initial ...

    8. Optical Coherence Tomography Guided Laser Treatment of Basal Cell Carcinoma

      Optical Coherence Tomography Guided Laser Treatment of Basal Cell Carcinoma
      The purpose of this pilot study is to examine the treatment basal cell carcinoma (BCC) with laser technology under the guidance of optical coherence tomography imaging (OCT). The laser modality that we plan to use is the long-pulse Nd:YAG 1064nm laser, which is a non-ablative laser already shown to effectively treat BCC. Laser treatment of BCC has limited precedent in the literature, but the addition of OCT has the ...

      Feasibility and safety of tethered capsule endomicroscopy in patients with Barrett’s esophagus in a multi-center study
      Background Aims Tethered capsule endomicroscopy (TCE) involves swallowing small tethered pill that implements optical coherence tomography (OCT) imaging, procuring high resolution images of the whole esophagus. Here, we demonstrate and evaluate the feasibility and safety of TCE and a portable OCT imaging system in patients with Barretts esophagus (BE) in a multi-center (5-site) clinical study. Methods Untreated patients with BE as per endoscopic biopsy diagnosis were eligible to participate in ...

      Continuous Monitoring and Management of Vaginal Health Via Multifunctional OCT/OCTA/OCE Endoscopy
      We have recently developed and optimized a vaginal Optical Coherence tomography /angiography endoscopy imaging system. This technology is able to obtain a comprehensive image of the vaginal epithelium, blood vessels, and lamina propria. The primary focus of this study is establishing the Optical Coherence Tomography system's capability of capturing vaginal changes that occur before and after menopause, as well as before and after treatment with fractional-CO2 laser therapy.

      Cohort profile: a collaborative multicentre study of retinal optical coherence tomography in 539 patients with neuromyelitis optica spectrum disorders
      Purpose Optical coherence tomography (OCT) captures retinal damage in neuromyelitis optica spectrum disorders (NMOSD). Previous studies investigating OCT in NMOSD have been limited by the rareness and heterogeneity of the disease. The goal of this study was to establish an image repository platform, which will facilitate neuroimaging studies in NMOSD. Here we summarise the profile of the Collaborative OCT in NMOSD repository as the initial effort in establishing this platform ...

      2D Ultrasonic Array-based Optical Coherence Elastography
      Acoustic radiation force optical coherence elastography (ARF-OCE) has been successfully implemented to characterize the biomechanical properties of soft tissues such as the cornea and the retina with high resolution using single-element ultrasonic transducers for ARF excitation. Most currently proposed OCE techniques, such as air-puff and ARF, have less capability to control the spatiotemporal information of the induced region of deformation, resulting in limited accuracy and low temporal resolution of the ...

      Advances in Doppler optical coherence tomography and angiography
      Since the first demonstration of Doppler optical coherence tomography (OCT) in 1997, several functional extensions of Doppler OCT have been developed, including velocimetry, angiogram, and optical coherence elastography. These functional techniques have been widely used in research and clinical applications, particularly in ophthalmology. Here, we review the principles, representative methods, and applications of different Doppler OCT techniques, followed by discussion on the innovations, limitations, and future directions of each of ...

      Combining Deep Learning With Optical Coherence Tomography Imaging to Determine Scalp Hair and Follicle Counts
      Background and Objectives One of the challenges in developing effective hair loss therapies is the lack of reliable methods to monitor treatment response or alopecia progression. In this study, we propose the use of optical coherence tomography (OCT) and automated deep learning to non‐invasively evaluate hair and follicle counts that may be used to monitor the success of hair growth therapy more accurately and efficiently.
