    2. Classification of basal cell carcinoma in human skin using machine learning and quantitative features captured by polarization sensitive optical coherence tomography

      Classification of basal cell carcinoma in human skin using machine learning and quantitative features captured by polarization sensitive optical coherence tomography
      We report the first fully automated detection of basal cell carcinoma (BCC), the most commonly occurring type of skin cancer, in human skin using polarization-sensitive optical coherence tomography (PS-OCT). Our proposed automated procedure entails building a machine-learning based classifier by extracting image features from the two complementary image contrasts offered by PS-OCT, intensity and phase retardation (PR), and selecting a subset of features that yields a classifier with the highest ...

    3. En Face Imaging of Epiretinal Membranes and the Retinal Nerve Fiber Layer Using Swept-Source Optical Coherence Tomography

      En Face Imaging of Epiretinal Membranes and the Retinal Nerve Fiber Layer Using Swept-Source Optical Coherence Tomography
      BACKGROUND AND OBJECTIVE: To describe en face swept-source optical coherence tomography (SS-OCT) imaging of epiretinal membranes (ERMs) and the underlying retinal nerve fiber layer (RNFL). PATIENTS AND METHODS: SS-OCT images were captured in nine eyes with ERMs. These SS-OCT en face images were qualitatively compared to spectral-domain OCT (SD-OCT) en face images. Using SS-OCT, en face images of the RNFL were obtained, if possible. RESULTS: En face SS-OCT images of ...

    5. Acute stent recoil and optimal balloon inflation strategy: an experimental study using real-time optical coherence tomography

      Acute stent recoil and optimal balloon inflation strategy: an experimental study using real-time optical coherence tomography
      Aims: Our aim was to evaluate stent expansion and acute recoil at deployment and post-dilatation, and the impact of post-dilatation strategies on final stent dimensions. Methods and results: Optical coherence tomography (OCT) was performed on eight bare metal platforms of drug-eluting stents (3.0 mm diameter, n=6 for each) during and after balloon inflation in a silicone mock vessel. After nominal-pressure deployment, a single long (30 sec) vs. multiple ...

    6. High-resolution contrast-enhanced optical coherence tomography in mice retinae

      High-resolution contrast-enhanced optical coherence tomography in mice retinae
      Optical coherence tomography (OCT) is a noninvasive interferometric imaging modality providing anatomical information at depths of millimeters and a resolution of micrometers. Conventional OCT images limit our knowledge to anatomical structures alone, without any contrast enhancement. Therefore, here we have, for the first time, optimized an OCT-based contrast-enhanced imaging system for imaging single cells and blood vessels in vivo inside the living mouse retina at subnanomolar sensitivity. We used bioconjugated ...

    7. New appraisals of Kyrieleis plaques: a multimodal imaging study

      New appraisals of Kyrieleis plaques: a multimodal imaging study
      Purpose Kyrieleis retinal periarteritis reflects the severe intraocular inflammation experienced by the eye. Its aetiology has not been well established, since only nine cases have been reported and there is no pathological study available in the literature. We determine the pathogenesis of Kyrieleis periarteritis based on interpretation of multimodal imaging findings. Methods Charts of patients with Kyrieleis arteritis seen between 2006 and 2014 were retrieved from eight uveitis referral centres ...

    8. Optical Coherence Tomography to Measure Sound-Induced Motions Within the Mouse Organ of Corti In Vivo

      Optical Coherence Tomography to Measure Sound-Induced Motions Within the Mouse Organ of Corti In Vivo
      The measurement of mechanical vibrations within the living cochlea is critical to understanding the first nonlinear steps in auditory processing, hair cell stimulation, and cochlear amplification. However, it has proven to be a challenging endeavor. This chapter describes how optical coherence tomography (OCT) can be used to measure vibrations within the tissues of the organ of Corti. These experimental measurements can be performed within the unopened cochlea of living mice ...

    9. Spectral-Domain Optical Coherence Tomography Angiography of Central Retinal Artery Occlusion

      Spectral-Domain Optical Coherence Tomography Angiography of Central Retinal Artery Occlusion
      The authors report the use of optical coherence tomography angiography (OCTA) to determine retinal blood flow in a patient with central retinal artery occlusion (CRAO). Spectral-domain OCTA (SD-OCTA) was performed on an eye with CRAO. En face vascular images were constructed using an optical microangiography algorithm. The retinal vasculature was clearly imaged with high fidelity; areas of perfused retina were identified with exquisite detail. This study supports use of OCTA ...

    11. High-speed spectral calibration by complex FIR filter in phase-sensitive optical coherence tomography

      High-speed spectral calibration by complex FIR filter in phase-sensitive optical coherence tomography
      Swept-laser sources offer a number of advantages for Phase-sensitive Optical Coherence Tomography (PhOCT). However, inter- and intra-sweep variability leads to calibration errors that adversely affect phase sensitivity. While there are several approaches to overcoming this problem, our preferred method is to simply calibrate every sweep of the laser. This approach offers high accuracy and phase stability at the expense of a substantial processing burden. In this approach, the Hilbert phase ...
