    2. Evaluation of Single-Impact-Induced Cartilage Degeneration by Optical Coherence Tomography

      Evaluation of Single-Impact-Induced Cartilage Degeneration by Optical Coherence Tomography
      Posttraumatic osteoarthritis constitutes a major cause of disability in our increasingly elderly population. Unfortunately, current imaging modalities are too insensitive to detect early degenerative changes of this disease. Optical coherence tomography (OCT) is a promising nondestructive imaging technique that allows surface and subsurface imaging of cartilage, at near-histological resolution, and is principally applicable in vivo during arthroscopy. Thirty-four macroscopically normal human cartilage-bone samples obtained from total joint replacements were subjected ...

    3. Optical coherence tomography applied to the evaluation of wear of composite resin for posterior teeth

      Optical coherence tomography applied to the evaluation of wear of composite resin for posterior teeth
      Resin composites are widely used as restorative materials due to their excellent aesthetical and mechanical properties. Posterior teeth are constantly submitted to occlusal stress and upon restoration require more resistant resins. The aim of this study was to analyze in vitro the wear suffered over time by restorations in resin composite in posterior teeth, by Optical Coherence Tomography (OCT). 30 molars had occlusal cavities prepared and were randomly divided into ...

    4. Optical coherence tomography: A new strategy to image planarian regeneration

      Optical coherence tomography: A new strategy to image planarian regeneration
      The planarian is widely used as a model for studying tissue regeneration. In this study, we used optical coherence tomography (OCT) for the real-time, high-resolution imaging of planarian tissue regeneration. Five planaria were sliced transversely to produce 5 head and 5 tail fragments. During a 2-week regeneration period, OCT images of the planaria were acquired to analyze the signal attenuation rates, intensity ratios, and image texture features (including contrast, correlation ...

    5. Visualization of Maculae and Membranous Semicircular Ducts in the Otic Capsule by Optical Coherence Tomography

      Visualization of Maculae and Membranous Semicircular Ducts in the Otic Capsule by Optical Coherence Tomography
      Objectives: (1) Show the possibility of using optical coherence tomography (OCT) to visualize the internal structure of the vestibule and semicircular canals with the bony capsule intact. (2) Study the effect of the decalcification. OCT is a nondestructive imaging modality that uses infrared light as it penetrates turbid biological tissue. Previously, OCT has been successfully used to visualize inside the cochlea in normal and abnormal inner ears. Methods: The OCT ...

    6. Identification of vessel wall anomalies in thoracic aortic aneurysms through optical coherence tomography and gradient-based strategies

      Identification of vessel wall anomalies in thoracic aortic aneurysms through optical coherence tomography and gradient-based strategies
      Optical Coherence Tomography is a natural candidate for imaging biological structures just under tissue surface. Human thoracic aorta from aneurysms reveal elastin disorders and smooth muscle cell alterations when visualizing the media layer of the aortic wall, which is only some tens of microns in depth from surface. The resulting images require a suitable processing to enhance interesting disorder features and to use them as indicators for wall degradation, converting ...

    7. Imaging of electro-kinetic properties of tissue using the amplitude and the phase of optical coherence tomography

      Imaging of electro-kinetic properties of tissue using the amplitude and the phase of optical coherence tomography
      The electric field induced optical changes (EIOC) measured by the optical coherence tomography (OCT) reflect the local electro-kinetic properties of the tissue. In this study we developed a method to use the phase of the complex OCT images to map EIOC in tissue samples. Switching the polarity of the electric field induced significant reversible changes in the phase of the complex OCT images. Since the resulting phase was degraded by ...

    8. Feature Of The Week 9/22/13: Lehigh University Researchers Investigate Space-Division Multiplexing for High-Speed Optical Coherence Tomography

      Feature Of The Week 9/22/13: Lehigh University Researchers Investigate Space-Division Multiplexing for High-Speed Optical Coherence Tomography
      High speed, high resolution and high sensitivity are desirable for optical coherence tomography (OCT). Here, we demonstrate a space-division multiplexing (SDM) technology that translates long coherence length of a commercially available wavelength tunable laser into high OCT imaging speed. We achieved an effective 800,000 A-scans/s imaging speed using a commercially available 100,000 Hz tunable vertical cavity surface-emitting laser (VCSEL) from Thorlabs Inc. A sensitivity of 94.6 ...

    9. Assessment of interfacial defects at composite restorations by swept source optical coherence tomography

      Assessment of interfacial defects at composite restorations by swept source optical coherence tomography
      In clinical dental practice, it is often difficult or even impossible to detect and assess interfacial adhesive defects at adhesive restorations by means of visual inspection or other established diagnostic methods. However, nondestructive optical coherence tomography (OCT) may provide a better picture in this diagnostic scenario. The aim of this study was to evaluate the suitability of swept source OCT (SS-OCT) for the nondestructive assessment of interfacial deficiencies at composite ...

    10. Evaluation of optical coherence tomography as a non-invasive diagnostic tool in cutaneous wound healing

      Evaluation of optical coherence tomography as a non-invasive diagnostic tool in cutaneous wound healing
      Background The monitoring of wound-healing processes is indispensable for the therapeutic effectiveness and improved care of chronic wounds. Histological sections provide the best morphological assessment of wound recovery, but cause further tissue destruction and increase the risk of infection. Therefore, it is reasonable to apply a diagnostic tool that allows a non-invasive and reliable observation of morphological changes in wound healing. Methods Optical coherence tomography (OCT) is an imaging technique ...

    11. Application of optical coherence tomography to non-destructively characterise rind breakdown disorder of ‘Nules Clementine’ mandarins

      Application of optical coherence tomography to non-destructively characterise rind breakdown disorder of ‘Nules Clementine’ mandarins
      The feasibility of optical coherence tomography (OCT) for imaging histological changes associated with the development of a progressive rind breakdown (RBD) disorder of Nules Clementine mandarin ( Citrus reticulate Blanco.) was investigated. The investigation utilised fruit with different levels of the disorder, carefully selected from a batch of fruit stored for eight weeks at 8 0.5 C. Images of healthy and RBD-affected intact mandarin fruit were acquired using a Thorlabs ...

    12. In vivo microcirculation imaging of the sub surface fingertip using correlation mapping optical coherence tomography (cmOCT)

      In vivo microcirculation imaging of the sub surface fingertip using correlation mapping optical coherence tomography (cmOCT)
      We describe a novel application of correlation mapping optical coherence tomography (cmOCT) for sub-surface fingerprint biometric identification. Fingerprint biometrics including automated fingerprint identification systems, are commonly used to recognise the fingerprint, since they constitute simple, effective and valuable physical evidence. Spoofing of biometric fingerprint devices can be easily done because of the limited information obtained from the surface topography. In order to overcome this limitation a potentially more secure source ...
