    2. Real-time OCT image denoising using a self-fusion neural network

      Real-time OCT image denoising using a self-fusion neural network
      Optical coherence tomography (OCT) has become the gold standard for ophthalmic diagnostic imaging. However, clinical OCT image-quality is highly variable and limited visualization can introduce errors in the quantitative analysis of anatomic and pathologic features-of-interest. Frame-averaging is a standard method for improving image-quality, however, frame-averaging in the presence of bulk-motion can degrade lateral resolution and prolongs total acquisition time. We recently introduced a method called self-fusion, which reduces speckle noise ...

    4. Birefringent tissue-mimicking phantom for polarization-sensitive optical coherence tomography imaging

      Birefringent tissue-mimicking phantom for polarization-sensitive optical coherence tomography imaging
      Significance: Tissue birefringence is an important parameter to consider when designing realistic, tissue-mimicking phantoms. Options for suitable birefringent materials that can be used to accurately represent tissue scattering are limited. Aim: To introduce a method of fabricating birefringent tissue phantoms with a commonly used material-polydimethylsiloxane (PDMS)-for imaging with polarization-sensitive optical coherence tomography (PS-OCT). Approach: Stretch-induced birefringence was characterized in PDMS phantoms made with varying curing ratios, and the resulting ...

    5. Investigation of Micro-motion Kinematics of Continuum Robots for Volumetric OCT and OCT-guided Visual Servoing

      Investigation of Micro-motion Kinematics of Continuum Robots for Volumetric OCT and OCT-guided Visual Servoing
      Continuum robots (CR) have been recently shown capable of micron-scale motion resolutions. Such motions are achieved through equilibrium modulation using indirect actuation for altering either internal preload forces or changing the cross-sectional stiffness along the length of a continuum robot. Previously reported, but unexplained, turning point behavior is modeled using two approaches. An energy minimization approach is first used to explain the source of this behavior. Subsequently, a kinematic model ...

    8. Intraoperative Optical Coherence Tomography - Normals

      Intraoperative Optical Coherence Tomography - Normals
      Optical coherence tomography (OCT) is an established technology for ophthalmic diagnosis which can perform noncontact, noninvasive, real time, cross-sectional imaging of the retina and anterior eye. OCT has displaced ophthalmoscopy and stereo-photography as the gold-standard for clinical assessment and documentation of retinal microanatomy including thickness, cystoid structures, subretinal fluid and retinal traction. Despite these benefits, new technologies can still benefit patients including increasing the resolution, imaging speed, and contrast of ...

    9. Advances in Optical Detection of Human-Associated Pathogenic Bacteria

      Advances in Optical Detection of Human-Associated Pathogenic Bacteria
      Bacterial infection is a global burden that results in numerous hospital visits and deaths annually. The rise of multi-drug resistant bacteria has dramatically increased this burden. Therefore, there is a clinical need to detect and identify bacteria rapidly and accurately in their native state or a culture-free environment. Current diagnostic techniques lack speed and effectiveness in detecting bacteria that are culture-negative, as well as options for in vivo detection. The ...

      Variability Within Optic Nerve Optical Coherence Tomography Measurements Distinguishes Papilledema From Pseudopapilledema
      Background: To report a linear risk score obtained using clock-hour optical coherence tomography (OCT) data from papilledema and pseudopapilledema nerves that differentiates between the 2 diagnoses with high sensitivity and specificity. Methods: Patients presenting to a single neuro-ophthalmologist with papilledema or pseudopapilledema were included for a retrospective review. The absolute consecutive difference in OCT retinal nerve fiber layer (RNFL) thickness between adjacent clock hours and the mean magnitude of thickness ...

    11. Image-guidance in ophthalmic surgery using optical coherence tomography (Thesis)

      Image-guidance in ophthalmic surgery using optical coherence tomography (Thesis)
      Ophthalmic surgery involves manipulation of layered tissue structures on milli- to micrometer scales. Traditional surgical microscopes provide a two-dimensional view of the surgical field with limited depth perception which precludes accurate depth-resolved visualization of surgically-induced tissue morphology. Optical coherence tomography (OCT) enables non-contact exogenous contrast-free imaging of subsurface tissue microstructures, and is currently the gold standard for ophthalmic clinical diagnostics. Over the last decade, translation of OCT technologies to applications ...

    12. Multimodality Imaging-Based Characterization of Regional Material Properties in a Murine Model of Aortic Dissection

      Multimodality Imaging-Based Characterization of Regional Material Properties in a Murine Model of Aortic Dissection
      hronic infusion of angiotensin-II in atheroprone ( ApoE / ) mice provides a reproducible model of dissection in the suprarenal abdominal aorta, often with a false lumen and intramural thrombus that thickens the wall. Such lesions exhibit complex morphologies, with different regions characterized by localized changes in wall composition, microstructure, and properties. We sought to quantify the multiaxial mechanical properties of murine dissecting aneurysm samples by combining in vitro extension-distension data with full-field ...

  2. About Vanderbilt University

    Vanderbilt University

    Vanderbilt University is a private, nonsectarian, coeducational research university in Nashville, Tennessee, USA. Founded in 1873, the university is named for shipping and rail magnate "Commodore" Cornelius Vanderbilt, who provided Vanderbilt its initial $1 million endowment despite having never been to the South. The Commodore hoped that his gift and the greater work of the university would help to heal the sectional wounds inflicted by the Civil War.
