    2. Associations between the Framingham Risk Score and coronary plaque characteristics as assessed by three-vessel optical coherence tomography

      Associations between the Framingham Risk Score and coronary plaque characteristics as assessed by three-vessel optical coherence tomography
      Objectives: This study sought to explore the association between the Framingham Risk Score (FRS) and coronary plaque characteristics assessed by optical coherence tomography (OCT) imaging. Background: Clinical prediction models are useful for identifying high-risk patients. However, coronary events often occur in individuals estimated to be at low risk. Methods: A total of 254 patients with coronary artery disease who underwent three-vessel OCT were divided into tertiles according to FRS. Nonculprit ...

    3. Attenuation Coefficients, Pixel Intensity, and Texture Analysis as Quantitative Parameters for Analyzing Optical Coherence Tomography Images of Vocal Fold Tissue (Thesis)

      Attenuation Coefficients, Pixel Intensity, and Texture Analysis as Quantitative Parameters for Analyzing Optical Coherence Tomography Images of Vocal Fold Tissue (Thesis)
      Optical coherence tomography is a promising technology to noninvasively assess vocal fold microanatomy. However, many studies using optical coherence tomography to evaluate vocal fold tissue are largely qualitative in nature and lack quantitative measures that might be useful in clinical decision-making. The goal of this thesis was to identify quantitative metrics that can be extracted from optical coherence tomography vocal fold imaging and applied to the surgical subspecialty of Laryngology ...

    4. Correlation of localized glaucomatous visual field defects and spectral domain optical coherence tomography retinal nerve fiber layer thinning using a modified structure–function map for OCT

      Correlation of localized glaucomatous visual field defects and spectral domain optical coherence tomography retinal nerve fiber layer thinning using a modified structure–function map for OCT
      Purpose To study the correlation between glaucomatous visual field (VF) defects assessed by standard automated perimetry (SAP) and peripapillary retinal nerve fiber layer (RNFL) thinning measured by spectral domain optical coherence tomography (OCT) using a modified OCT-based peripapillary RNFL structurefunction map. Patients and methods Perimetric glaucoma patients and age-matched normal control subjects were recruited from a university hospital clinic. All eyes underwent testing with the Spectralis spectral domain OCT and ...

    6. An Elastic Second Skin

      An Elastic Second Skin
      We report the synthesis and application of an elastic, wearable crosslinked polymer layer (XPL) that mimics the properties of normal, youthful skin. XPL is made of a tunable polysiloxane-based material that can be engineered with specific elasticity, contractility, adhesion, tensile strength and occlusivity. XPL can be topically applied, rapidly curing at the skin interface without the need for heat- or light-mediated activation. In a pilot human study, we examined the ...

    7. Massachusetts General Hospital Receives NIH Grant for Octology: Histology using Optical Coherence Tomography

      Massachusetts General Hospital Receives NIH Grant for Octology: Histology using Optical Coherence Tomography
      Massachusetts General Hospital Receives a 2016 NIH Grant for $253,600 for Octology: Histology using Optical Coherence Tomography.The principal investigator is Burce Fischl. The program began in 2015 and ends in 2017. Below is a summary of the proposed work. While histology remains the gold standard for assessing human neuroanatomy, the procedures for sectioning and hand mounting tissue for microscopic imaging are not substantially different than they were 100 ...

    9. Polarization sensitive optical coherence microscopy for brain imaging

      Polarization sensitive optical coherence microscopy for brain imaging
      Optical coherence tomography (OCT) and optical coherence microscopy (OCM) have demonstrated the ability to investigate cyto- and myelo-architecture in the brain. Polarization-sensitive OCT provides sensitivity to additional contrast mechanisms, specifically the birefringence of myelination and, therefore, is advantageous for investigating white matter fiber tracts. In this Letter, we developed a polarization-sensitive optical coherence microscope (PS-OCM) with a 3.5 m axial and 1.3 m transverse resolution to investigate fiber ...

    10. Optical Coherence Tomography: Role in Percutaneous Coronary Intervention (Book Chapter)

      Optical Coherence Tomography: Role in Percutaneous Coronary Intervention (Book Chapter)
      Optical coherence tomography (OCT) is an imaging modality that utilizes back-reflection of near-infrared light. Superior resolution intra-coronary imaging, including assessment of plaque morphology and characteristics as well as imaging stents and post-stent complications have made OCT a powerful research tool, and more recently a clinical tool for guidance of PCI. Visualization of coronary lesions with OCT and their characterization as lipid-rich, fibrous, or fibro-calcific plaque can influence percutaneous coronary intervention ...

    14. Hybrid intravascular imaging: recent advances, technical considerations, and current applications in the study of plaque pathophysiology

      Hybrid intravascular imaging: recent advances, technical considerations, and current applications in the study of plaque pathophysiology
      Cumulative evidence from histology-based studies demonstrate that the currently available intravascular imaging techniques have fundamental limitations that do not allow complete and detailed evaluation of plaque morphology and pathobiology, limiting the ability to accurately identify high-risk plaques. To overcome these drawbacks, new efforts are developing for data fusion methodologies and the design of hybrid, dual-probe catheters to enable accurate assessment of plaque characteristics, and reliable identification of high-risk lesions. Today ...
