      Virtual Histology Optical Coherence Tomography Imaging of Orbital Rotational Atherectomy for Calcified Peripheral Arterial Disease
      A 72-year-old man with critical limb ischemia of the right lower extremity was referred for revascularization. His peripheral angiography showed severely calcified total occlusions of the right posterior tibial artery, peroneal arteries, and dorsalis pedis, with severe stenosis of the anterior tibial artery with collaterals (Figures 1A-1D). In order to assess the vascular effects of rotational orbital atherectomy, we performed intravascular imaging with virtual histology intravascular optical coherence tomography (VH-IVOCT ...

      Scattering Angle Resolved Optical Coherence Tomography Detects Early Changes in 3xTg Alzheimer's Disease Mouse Model
      Purpose : Clinical intensity-based optical coherence tomographic retinal imaging is unable to resolve some of the earliest changes to Alzheimer's disease (AD) neurons. The aim of this pilot study was to demonstrate that scattering-angle-resolved optical coherence tomography (SAR - OCT), which is sensitive to changes in light scattering angle, is a candidate retinal imaging modality for early AD detection. SAR-OCT signal data may be sensitive to changes in intracellular constituent morphology ...

      Assessment of Vascular Patency and Inflammation with Intravascular Optical Coherence Tomography in Patients with Superficial Femoral Artery Disease Treated with Zilver PTX Stents
      Purpose Zilver PTX nitinol self-expanding drug-eluting stent with paclitaxel coating is effective for treatment of superficial femoral artery (SFA) disease. However, as with any stent, it induces a measure of vascular inflammatory response. The current clinical trial (NCT02734836) aimed to assess vascular patency, remodeling, and inflammatory markers with intravascular optical coherence tomography (OCT) in patients with SFA disease treated with Zilver PTX stents. Methods Serial OCT examinations were performed in ...

      Laser brain cancer surgery in a xenograft model guided by optical coherence tomography
      Higher precision surgical devices are needed for tumor resections near critical brain structures. The goal of this study is to demonstrate feasibility of a system capable of precise and bloodless tumor ablation. An image-guided laser surgical system is presented for excision of brain tumors in vivo in a murine xenograft model. The system combines optical coherence tomography (OCT) guidance with surgical lasers for high-precision tumor ablation (Er:YAG) and microcirculation ...

      Scattering-Angle-Resolved Optical Coherence Tomography of a Hypoxic Mouse Retina Model
      Several studies have noted a correlation between retinal degeneration and traumatic encephalopathy (TE) making the retina a leading candidate for detection and assessment. Scattering-angle-resolved optical coherence tomography (SAR-OCT) is a candidate imaging modality to detect sub-resolution changes in retinal microstructure. SAR-OCT images of murine retinas that experience a hypoxic insult euthanasia by isoflurane overdoseare presented. A total of 4 SAR-OCT measurement parameters are reported in 6 longitudinal experiments: blood flow ...

      Design Considerations for Murine Retinal Imaging Using Scattering Angle Resolved Optical Coherence Tomography
      Optical coherence tomography (OCT), an optical imaging approach enabling cross-sectional analysis of turbid samples, is routinely used for retinal imaging in human and animal models of diseases affecting the retina. Scattering angle resolved (SAR-)OCT has previously been demonstrated as offering additional contrast in human studies, but no SAR-OCT system has been reported in detail for imaging the retinas of mice. An optical model of a mouse eye was designed ...

      Understanding and improving optical coherence tomography imaging depth in selective laser sintering nylon 12 parts and powder
      Optical coherence tomography (OCT) has shown promise as a process sensor in selective laser sintering (SLS) due to its ability to yield depth-resolved data not attainable with conventional sensors. However, OCT images of nylon 12 powder and nylon 12 components fabricated via SLS contain artifacts that have not been previously investigated in the literature. A better understanding of light interactions with SLS powder and components is foundational for further research ...

      In situ process monitoring in selective laser sintering using optical coherence tomography
      Selective laser sintering (SLS) is an efficient process in additive manufacturing that enables rapid part production from computer-based designs. However, SLS is limited by its notable lack ofin situprocess monitoring when compared with other manufacturing processes. We report the incorporation of optical coherence tomography (OCT) into an SLS system in detail and demonstrate access to surface and subsurface features. Video frame rate cross-sectional imaging reveals areas of sintering uniformity and ...

      Impact of Ticagrelor and Aspirin versus Clopidogrel and Aspirin in Symptomatic Patients with Peripheral Arterial Disease: Thrombus Burden Assessed by Optical Coherence Tomography
      Purpose To compare OCT identified white thrombus decline, neointimal hyperplasia and clinical outcomes of patients treated with ticagrelor plus aspirin with those patients treated with clopidogrel plus aspirin after peripheral interventions. Background Ticagrelor is a potent platelet inhibitor. In patients with coronary artery disease, ticagrelor and aspirin demonstrated reduced rates of stent thrombosis, compared to aspirin and clopidogrel. The clinical importance of potent antiplatelet inhibition after peripheral endovascular interventions is ...

      Advances in Brain Tumor Surgery for Glioblastoma in Adults
      Glioblastoma (GBM) is the most common primary intracranial neoplasia, and is characterized by its extremely poor prognosis. Despite maximum surgery, chemotherapy, and radiation, the histological heterogeneity of GBM makes total eradication impossible, due to residual cancer cells invading the parenchyma, which is not otherwise seen in radiographic images. Even with gross total resection, the heterogeneity and the dormant nature of brain tumor initiating cells allow for therapeutic evasion, contributing to ...
