    1. Optical coherence tomography angiography to evaluate murine fetal brain vasculature changes caused by prenatal exposure to nicotine

      Optical coherence tomography angiography to evaluate murine fetal brain vasculature changes caused by prenatal exposure to nicotine
      Maternal smoking causes several defects ranging from intrauterine growth restriction to sudden infant death syndrome and spontaneous abortion. While several studies have documented the effects of prenatal nicotine exposure in development and behavior, acute vasculature changes in the fetal brain due to prenatal nicotine exposure have not been evaluated yet. This study uses correlation mapping optical coherence angiography to evaluate changes in fetal brain vasculature flow caused by maternal exposure ...

    2. Heartbeat OCE: corneal biomechanical response to simulated heartbeat pulsation measured by optical coherence elastography

      Heartbeat OCE: corneal biomechanical response to simulated heartbeat pulsation measured by optical coherence elastography
      Significance: It is generally agreed that the corneal mechanical properties are strongly linked to many eye diseases and could be used to assess disease progression and response to therapies. Elastography is the most notable method of assessing corneal mechanical properties, but it generally requires some type of external excitation to induce a measurable displacement in the tissue. Aim: We present Heartbeat Optical Coherence Elastography (Hb-OCE), a truly passive method that ...

    3. Clinical Corneal Optical Coherence Elastography Measurement Precision: Effect of Heartbeat and Respiration

      Clinical Corneal Optical Coherence Elastography Measurement Precision: Effect of Heartbeat and Respiration
      Purpose : Normal physiological movements (e.g., respiration and heartbeat) induce eye motions during clinical measurements of human corneal biomechanical properties using optical coherence elastography (OCE). We quantified the effects of respiratory and cardiac-induced eye motions on clinical corneal OCE measurement precision and repeatability. Methods : Corneal OCE was performed using low-force, micro-air-pulse tissue stimulation and high-resolution phase-sensitive optical coherence tomography (OCT) imaging. Axial surface displacements of the corneal apex were measured ...

    4. Multimodal quantitative optical elastography of the crystalline lens with optical coherence elastography and Brillouin microscopy

      Multimodal quantitative optical elastography of the crystalline lens with optical coherence elastography and Brillouin microscopy
      Assessing the biomechanical properties of the crystalline lens can provide crucial information for diagnosing disease and guiding precision therapeutic interventions. Existing noninvasive methods have been limited to global measurements. Here, we demonstrate the quantitative assessment of the elasticity of crystalline lens with a multimodal optical elastography technique, which combines dynamic wave-based optical coherence elastography (OCE) and Brillouin microscopy to overcome the drawbacks of individual modalities. OCE can provide direct measurements ...

    5. Laser-induced elastic wave classification: thermoelastic versus ablative regimes for all-optical elastography applications

      Laser-induced elastic wave classification: thermoelastic versus ablative regimes for all-optical elastography applications
      Significance : Shear wave optical coherence elastography is an emerging technique for characterizing tissue biomechanics that relies on the generation of elastic waves to obtain the mechanical contrast. Various techniques, such as contact, acoustic, and pneumatic methods, have been used to induce elastic waves. However, the lack of higher-frequency components within the elastic wave restricts their use in thin samples. The methods also require moving parts and/or tubing, which therefore ...

    9. Dynamic optical coherence elastography: Emerging tool for noninvasive quantification of mechanical properties of ocular tissues

      Dynamic optical coherence elastography: Emerging tool for noninvasive quantification of mechanical properties of ocular tissues
      Optical coherence elastography (OCE) is an emerging method for noninvasive quantification of tissue viscoelastic properties. The underlying technology is based on Optical Coherence Tomography (OCT) imaging and analysis of external (or internal) force-induced mechanical waves propagating through the tissue. In this presentation, I will overview recent progress made in my lab on quantification of mechanical properties of ocular tissues (such as cornea and the lens of the eye) using OCE ...

    10. Assessing the Acute Effects of Prenatal Synthetic Cannabinoid Exposure on Murine Fetal Brain Vasculature Using Optical Coherence Tomography

      Assessing the Acute Effects of Prenatal Synthetic Cannabinoid Exposure on Murine Fetal Brain Vasculature Using Optical Coherence Tomography
      Marijuana is one of the most commonly abused substances during pregnancy. Synthetic cannabinoids (SCBs) are a group of heterogeneous compounds that are 40‐ to 600‐fold more potent than ∆ 9 ‐tetrahydrocannabinol , the major psychoactive component of marijuana. With SCBs being legally available for purchase and the prevalence of unplanned pregnancies, the possibility of prenatal exposure to SCBs is high. However, the effects of prenatal SCB exposure on embryonic brain development ...

    11. Optical coherence elastography of cold cataract in porcine lens

      Optical coherence elastography of cold cataract in porcine lens
      Cataract is one of the most prevalent causes of blindness around the world. Understanding the mechanisms of cataract development and progression is important for clinical diagnosis and treatment. Cold cataract has proven to be a robust model for cataract formation that can be easily controlled in the laboratory. There is evidence that the biomechanical properties of the lens can be significantly changed by cataract. Therefore, early detection of cataract, as ...

    13. Assessing the biomechanical properties of the porcine crystalline lens as a function of intraocular pressure with optical coherence elastography

      Assessing the biomechanical properties of the porcine crystalline lens as a function of intraocular pressure with optical coherence elastography
      In this study, we investigated the relationship between the biomechanical properties of the crystalline lens and intraocular pressure (IOP) using a confocal acoustic radiation force (ARF) and phase-sensitive optical coherence elastography (OCE) system. ARF induced a small displacement at the apex of porcine lenses in situ at various artificially controlled IOPs. Maximum displacement, relaxation rate, and Youngs modulus were utilized to assess the stiffness of the crystalline lens. The results ...

    14. Integrated optical coherence tomography and multielement ultrasound transducer probe for shear wave elasticity imaging of moving tissues

      Integrated optical coherence tomography and multielement ultrasound transducer probe for shear wave elasticity imaging of moving tissues
      Accurate measurements of microelastic properties of soft tissues in-vivo using optical coherence elastography can be affected by motion artifacts caused by cardiac and respiratory cycles. This problem can be overcome using a multielement ultrasound transducer probe where each ultrasound transducer is capable of generating acoustic radiation force (ARF) and, therefore, creating shear waves in tissue. These shear waves, produced during the phase of cardiac and respiratory cycles when tissues are ...

    15. Modified wavelength scanning interferometry for simultaneous tomography and topography of the cornea with Fourier domain optical coherence tomography

      Modified wavelength scanning interferometry for simultaneous tomography and topography of the cornea with Fourier domain optical coherence tomography
      Visual acuity is dependent on corneal shape and size. A minor variation in surface geometry can cause a deformation of corneal geometry, which affects its optical performance. In this work we demonstrate an algorithm for the simultaneous measurement of corneal tomography and topography with a traditional point-scanning Fourier domain optical coherence tomography (FD-OCT) system. A modified wavelength scanning interferometry (mWSI) algorithm enabled topographical evaluation of the surface with nanometer-scale resolution ...
