    3. Optical Coherent Tomography to guide below-the-knee endovascular interventions

      Optical Coherent Tomography to guide below-the-knee endovascular interventions

      Peripheral arterial disease remains a common cause of leg amputations causing significant morbidity and mortality. Data regarding below-the-knee endovascular interventions is scarce while long-term patency rates via different endovascular revascularization modalities remain limited. OCT offers excellent three dimension endothelial visualization; however its value to guide peripheral interventions has not been studied. We describe the use of OCT to guide endovascular below-the-knee interventions in order to achieve excellent OCT results.

    4. A Functional Anatomic Defect of the Cystic Fibrosis Airway

      A Functional Anatomic Defect of the Cystic Fibrosis Airway

      Rationale: The mechanisms underlying cystic fibrosis (CF) lung disease pathogenesis are unknown. Objective: To establish mechanisms linking anion transport with the functional microanatomy, we evaluated normal and CF piglet trachea, as well as adult swine trachea in the presence of selective anion inhibitors. Methods: We investigated airway functional microanatomy using micro-optical coherence tomography, a new imaging modality that concurrently quantifies multiple functional parameters of airway epithelium in a co-localized fashion. Main Results: Tracheal explants from wild type swine demonstrated a direct link between periciliary liquid (PCL) hydration and mucociliary transport (MCT) rates, a relationship frequently invoked but never experimentally confirmed ...

    5. Use of Optical Coherence Tomography During Superficial Femoral Artery Interventions

      Use of Optical Coherence Tomography During Superficial Femoral Artery Interventions

      Superficial femoral artery (SFA) disease accounts for approximately 40% of the symptomatic peripheral arterial disease and remains a common cause of critical limb ischemia and lower-extremity amputation. Optical coherence tomography (OCT) has been extensively studied in the coronary circulation; however, its use in the peripheral arterial circulation is scarce. We present two cases of OCT use as an ancillary imaging tool during SFA endovascular interventions

    6. Breaking diffraction limit of lateral resolution in optical coherence tomography

      Breaking diffraction limit of lateral resolution in optical coherence tomography

      Quantitative imaging of biomedical specimens is essential in biomedical study and diagnosis. Given excellent capability in three-dimensional (3D) imaging, optical coherence tomography (OCT) has been extensively used in ophthalmic imaging, vascular medicine, dermatological study, etc. Lateral resolution of the OCT is light diffraction limited, which precludes the feasibility of quantitative assessment of individual cells. In this paper, we demonstrated the feasibility of breaking diffraction-limit in OCT imaging through virtually structured detection (VSD). OCT examination of optical resolution target verified resolution doubling in the VSD based OCT imaging. Super-resolution OCT identification of individual frog photoreceptors was demonstrated to verify the potential ...

    8. In vivo Optical Coherence Tomography of Light-Driven Melanosome Translocation in Retinal Pigment Epithelium

      In vivo Optical Coherence Tomography of Light-Driven Melanosome Translocation in Retinal Pigment Epithelium

      Optical coherence tomography (OCT) may revolutionize fundamental investigation and clinical management of age-related macular degeneration and other eye diseases. However, quantitative OCT interpretation is hampered due to uncertain sub-cellular correlates of reflectivity in the retinal pigment epithelium (RPE) and photoreceptor. The purpose of this study was twofold: 1) to test OCT correlates in the RPE, and 2) to demonstrate the feasibility of longitudinal OCT monitoring of sub-cellular RPE dynamics. A high resolution OCT was constructed to achieve dynamic imaging of frog eyes, in which light-driven translocation of RPE melanosomes occurred within the RPE cell body and apical processes. Comparative histological ...

      Inner Macular Hyperreflectivity Demonstrated by Optical Coherence Tomography in Niemann-Pick Disease

      We describe spectral-domain optical coherence tomography (OCT; Heidelberg Spectralis) imaging of 3 patients with Niemann-Pick disease type B. This expands the range of previously reported anatomical correlates of the ophthalmoscopic macular halo surrounding the “cherry-red spot.”

  2. About University of Alabama

    University of Alabama

    The University of Alabama (also known as Alabama, UA, or colloquially as 'Bama) is a public coeducational university located in Tuscaloosa, Alabama, USA. Founded in 1831, UA is the flagship school of the University of Alabama System. Within Alabama, it is often called the Capstone. UA is the senior and the largest in terms of enrollment of the state's major research universities, the others being academic and athletic rival Auburn University and fellow UA System institutions the University of Alabama in Huntsville (UAH) and the University of Alabama at Birmingham (UAB). Outside the state, it is well known for the fact that its athletic teams are nicknamed the "Crimson Tide" (crimson being one of the school colors).   The University of Alabama offers programs of study in 12 academic divisions leading to bachelor's, master's, Education Specialist, and doctoral degrees. The only publicly-supported law school in Alabama is at UA. Other academic programs unavailable elsewhere in Alabama include doctoral programs in anthropology, library and information studies, metallurgical and material engineering, music, Romance languages, and social work.  As of fall 2007, Alabama has an enrollment of 25,580 students and its president is Dr. Robert Witt. The University of Alabama has the highest ranking in the 2008 edition of the US News and World Report: America's Best Colleges of any university in the state of Alabama."
