    2. 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 ...

    3. 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 ...

    4. Variability Within Optic Nerve Optical Coherence Tomography Measurements Distinguishes Papilledema From Pseudopapilledema

      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 ...

    5. 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 ...

    6. 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 ...

    7. Researchers advance image-guided robotic surgical tools for delicate eye procedures

      Researchers advance image-guided robotic surgical tools for delicate eye procedures
      Molecular, gene and cell-based therapies targeting eye diseases could prevent and potentially reverse cell degeneration that leads to loss of sight. However, delivering injections safely and accurately into targeted ocular layers remain concerns that affect the advancement of life-changing new treatments. To address the safety and reliability challenges, researchers in the Vanderbilt Institute for Surgery and Engineering are joining their expertise to enable the use of optical coherence tomography (OCT ...

    8. Review of methods and applications of attenuation coefficient measurements with optical coherence tomography

      Review of methods and applications of attenuation coefficient measurements with optical coherence tomography
      The optical attenuation coefficient (AC), an important tissue parameter that measures how quickly incident light is attenuated when passing through a medium, has been shown to enable quantitative analysis of tissue properties from optical coherence tomography (OCT) signals. Successful extraction of this parameter would facilitate tissue differentiation and enhance the diagnostic value of OCT. In this review, we discuss the physical and mathematical basis of AC extraction from OCT data ...

    9. Handheld spectrally encoded coherence tomography and reflectometry for motion-corrected ophthalmic optical coherence tomography and optical coherence tomography angiography

      Handheld spectrally encoded coherence tomography and reflectometry for motion-corrected ophthalmic optical coherence tomography and optical coherence tomography angiography
      Optical coherence tomography (OCT) is the gold standard for quantitative ophthalmic imaging. The majority of commercial and research systems require patients to fixate and be imaged in a seated upright position, which limits the ability to perform ophthalmic imaging in bedridden or pediatric patients. Handheld OCT devices overcome this limitation, but image quality often suffers due to a lack of real-time aiming and patient eye and photographer motion. We describe ...

    10. Photothermal Optical Coherence Tomography of Anti-Angiogenic Treatment in the Mouse Retina Using Gold Nanorods as Contrast Agents

      Photothermal Optical Coherence Tomography of Anti-Angiogenic Treatment in the Mouse Retina Using Gold Nanorods as Contrast Agents
      Purpose : Optical coherence tomography (OCT) is widely used for ocular imaging in clinical and research settings. OCT natively provides structural information based on the reflectivity of the tissues it images. We demonstrate the utility of photothermal OCT (PTOCT) imaging of gold nanorods (GNR) in the mouse retina in vivo in the laser-induced choroidal neovascularization (LCNV) model to provide additional image contrast within the lesion. Methods : Wild-type C57BL/6 mice were ...

  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.
