    2. Heart-rate sensitive optical coherence angiography for measuring vascular changes due to posttraumatic brain injury in micecal coherence tomography findings in Parkinson's disease

      Heart-rate sensitive optical coherence angiography for measuring vascular changes due to posttraumatic brain injury in micecal coherence tomography findings in Parkinson's disease
      Traumatic brain injury (TBI) results in direct vascular disruption, triggering edema, and reduction in cerebral blood flow. Therefore, understanding the pathophysiology of brain microcirculation following TBI is important for the development of effective therapies. Optical coherence angiography (OCA) is a promising tool for evaluating TBI in rodent models. We develop an approach to OCA that uses the heart-rate frequency to discriminate between static tissue and vasculature. This method operates on ...

    3. Dynamic measurement of the optical properties of bovine enamel demineralization models using four-dimensional optical coherence tomography

      Dynamic measurement of the optical properties of bovine enamel demineralization models using four-dimensional optical coherence tomography
      Dental enamel mineral loss is multifactorial and is consequently explored using a variety of in vitro models. Important factors include the presence of acidic pH and its specific ionic composition, which can both influence lesion characteristics. Optical coherence tomography (OCT) has been demonstrated as a promising tool for studying dental enamel demineralization. However, OCT-based characterization and comparison of demineralization model dynamics are challenging without a consistent experimental environment. Therefore, an ...

    6. Insights into the spatial distribution of lipid-rich plaques in relation to coronary artery bifurcations: an in-vivo optical coherence tomography study

      Insights into the spatial distribution of lipid-rich plaques in relation to coronary artery bifurcations: an in-vivo optical coherence tomography study
      Objectives: The aim of this study was to investigate the spatial location of vulnerable plaques at coronary artery bifurcations using frequency domain-optical coherence tomography. Background: In-vivo data on geometric location of vulnerable plaques in relation to coronary bifurcation are limited. Materials and methods: A total of 40 patients with left anterior descending artery bifurcation were studied. Plaque characteristics in five regions in relation to a side branch were compared: opposite ...

    7. Multi-system comparison of optical coherence tomography performance with point spread function phantoms

      Multi-system comparison of optical coherence tomography performance with point spread function phantoms
      Point spread function (PSF) phantoms based on unstructured distributions of sub-resolution particles in a transparent matrix have proven effective for evaluating resolution and its spatial variation in optical coherence tomography (OCT) systems. Measurements based on PSF phantoms have the potential to become a standard test method for consistent, objective and quantitative inter-comparison of OCT system performance. Towards this end, we have evaluated three PSF phantoms and investigated their ability to ...

      OCT Phantoms Survey: Please share your opinions!
      Earlier this year, the OCT Phantoms Initiative began by posting a survey to better understand the interests and needs for phantoms (controlled test objects) in the OCT community. We thank everyone for all the responses thus far. But if you havent had a chance to fill out the survey, we would be grateful to hear from you. It should only take about 5 minutes of your time. We will be ...

    9. Visualization of magnetic microcapsules in liquid by optical coherent tomography and control of their arrangement via external magnetic field

      Visualization of magnetic microcapsules in liquid by optical coherent tomography and control of their arrangement via external magnetic field
      Optical coherence tomography (OCT) is a new, non-invasive, noncontact in vivo imaging technology. We demonstrated that the OCT can be used as a sufficient technique for nanocomposite microcapsule visualization in a liquid medium. As a model system we choose a water/glycerol mixture with viscosity in a variable range from 1.01 to 1.41103 mPa s, including viscosity of a blood plasma. We have found that tomography spatial resolution ...

    10. Optical Coherence Tomography Detection of Neurodegeneration in Multiple Sclerosis

      Optical Coherence Tomography Detection of Neurodegeneration in Multiple Sclerosis
      The pathophysiology of multiple sclerosis (MS) is typically characterised by inflammation and demyelination leading to neurodegeneration, which is associated with disability and the progressive stages of MS. The visual system is a valuable tool for studying neurodegeneration and potential neuroprotection in the central nervous system due to its ease of accessibility. Optical coherence tomography (OCT) is a non-invasive tool, which can be used to measure the thickness of the retinal ...

      Three-dimensional calibration targets for optical coherence tomography
      The recent expansion of clinical applications for optical coherence tomography (OCT) is driving the development of approaches for consistent image acquisition. There is a simultaneous need for time-stable, easy-to-use imaging targets for calibration and standardization of OCT devices. We present calibration targets consisting of three-dimensional structures etched into nanoparticle-embedded resin. Spherical iron oxide nanoparticles with a predominant particle diameter of 400 nm were homogeneously dispersed in a two part polyurethane ...
