    2. Multimodal imaging including spectral-domain optical coherence tomography and confocal near-infrared reflectance for characterization of lacquer cracks in highly myopic eyes

      Multimodal imaging including spectral-domain optical coherence tomography and confocal near-infrared reflectance for characterization of lacquer cracks in highly myopic eyes
      Purpose To compare multimodal imaging in detecting lacquer cracks in highly myopic eyes, and to correlate these findings with those of spectral-domain optical coherence tomography (SD-OCT). Methods An observational case series study. Patients with a refractive error worse than 8 diopters and lacquer cracks were recruited. The rates of detection of the lacquer cracks using multimodal imaging including near-infrared reflectance (NIR) imaging, fundus autofluorescence (FAF) imaging, and fluorescence angiography (FA ...

    3. 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 ...

    4. Investigation of temporal vascular effects induced by focused ultrasound treatment with speckle-variance optical coherence tomography

      Investigation of temporal vascular effects induced by focused ultrasound treatment with speckle-variance optical coherence tomography
      Focused ultrasound (FUS) can be used to locally and temporally enhance vascular permeability, improving the efficiency of drug delivery from the blood vessels into the surrounding tissue. However, it is difficult to evaluate in real time the effect induced by FUS and to noninvasively observe the permeability enhancement. In this study, speckle-variance optical coherence tomography (SVOCT) was implemented for the investigation of temporal effects on vessels induced by FUS treatment ...

    5. Deferoxamine retinopathy: spectral domain-optical coherence tomography findings

      Deferoxamine retinopathy: spectral domain-optical coherence tomography findings
      Background To describe the spectral domain optical coherence tomography (SD-OCT) findings of a patient who developed pigmentary retinopathy following high-dose deferoxamine administration. Case presentation A 34-year-old man with thalassemia major complained of nyctalopia and decreased vision following high-dose intravenous deferoxamine to treat systemic iron overload. Fundus examination revealed multiple discrete hypo-pigmented lesions at the posterior pole and mid-peripheral retina. Recovery was partial following cessation of desferrioxamine six weeks later. A ...

    6. Examination of ceramic/enamel interfacial debonding using acoustic emission and optical coherence tomography

      Examination of ceramic/enamel interfacial debonding using acoustic emission and optical coherence tomography
      Objective This study investigates monitored micro-crack growth and damage in the ceramic/enamel adhesive interface using the acoustic emission (AE) technique with optical coherence tomography (OCT) under fatigue shear testing. Methods Shear bond strength (SBS) was measured first with eight prepared ceramic/enamel adhesive specimens under static loads. The fatigue shear testing was performed with three specimens at each cyclic load according to a modified ISO14801 method, applying at 80 ...

    7. Region segmentation in 3-D optical coherence tomography images

      Region segmentation in 3-D optical coherence tomography images
      This paper describes a novel region segmentation method created to enhance spatial relationships in 3-D optical coherence tomography (OCT) images. To reduce the noise and distortion problems in low-resolution OCT images, previous work used the mean value and an enhanced-fuzzy-c-mean algorithm to cluster pixels in 2-D OCT images and find the edge between different clustered regions. To utilize more spatial relationships and to reduce computation time, the proposed method uses ...

    8. A pseudo-spectrum reconstruction method for reducing saturation artifact inspectral-domain optical coherence tomography

      A pseudo-spectrum reconstruction method for reducing saturation artifact inspectral-domain optical coherence tomography
      Saturation artifact is a significant image noise due to the limited detectable maximum light intensity of the CCD camera in the spectrometer module of spectral-domain optical coherence tomography (SD-OCT). This effect makes the OCT image appear with saturation noise in certain areas along with even more obvious vertical lines of noise. The unwanted artifacts cover the real sample structure information and can render the image unclear. This artifact problem is ...

    10. Noninvasive characterization of fractional photothermolysis induced by ablative and non-ablativelasers with optical coherence tomography

      Noninvasive characterization of fractional photothermolysis induced by ablative and non-ablativelasers with optical coherence tomography
      In this study, an optical coherence tomography (OCT) system is implemented for the noninvasive characterization of photothermolysis in human skin induced by ablative fractional lasers (AFLs) and non-ablative fractional lasers (NAFLs). With OCT imaging, microthermal zones (MTZs) induced by fractional lasers can be noninvasively visualized, and the size of induced MTZs can be quantitatively evaluated. According to the OCT results, the center region of the induced MTZ corresponds to weaker ...
