    Explore Article Respiratory Research (Jan 23 2010) Bronchoscopy

    Distribution of airway narrowing responses across generations and at branching points, assessed in vitro by anatomical optical coherence tomography Background Previous histological and imaging studies have shown the presence of variability in the degree of bronchoconstriction of airways sampled at different locations in the lung (i.e., heterogeneity). Heterogeneity can occur at different airway generations and at branching points in the bronchial tree. Whilst heterogeneity has been detected by previous experimental approaches its spatial relationship either within or between airways is unknown. Methods In this study, distribution of airway narrowing ... (Read Full Article)

    Airway Narrowing Assessed by Anatomical Optical Coherence Tomography In Vitro: Dynamic Airway Wall Morphology and Function Regulation of airway caliber by lung volume or bronchoconstrictor stimulation is dependent on physiological, structural and mechanical events within the airway wall, including airway smooth muscle (ASM) contraction, deformation of the mucosa and cartilage, and tensioning of elastic matrices linking wall components. Despite close association between events in the airway wall and the resulting airway caliber these have typically been studied separately: the former primarily using histological approaches, the latter ...

    A Method Of Providing Quantitative Information About The Lower Airways Of A Lung (Wo 2009/059368) The present disclosure provides a method of providing quantitative information about a property of the lower airways of a lung using optical coherence tomography. The method comprises inserting a probe head of an anatomical optical coherence tomography device into the lower airways. Further, the method comprises directing light to, and receiving reflected light from, an internal wall portion of the lower airways. The light is suitable for optical coherence tomography. ...

  6. Audio frequency in vivo optical coherence elastography

    Explore Article Institute of Physics (May 5 2009)

    Abstract. We present a new approach to optical coherence elastography (OCE), which probes the local elastic properties of tissue by using optical coherence tomography to measure the effect of an applied stimulus in the audio frequency range. We describe the approach, based on analysis of the Bessel frequency spectrum of the interferometric signal detected from scatterers undergoing periodic motion in response to an applied stimulus. We present quantitative results of ... (Read Full Article)

    Anatomical optical coherence tomography in the human upper airway (Thesis) This thesis describes the development, clinical validation and initial application of a technique for taking measurements of the shape and dimensions of the human upper airway, called anatomical optical coherence tomography (aOCT). The technique uses a transparent catheter containing a rotating optical probe which is introduced transnasally and positioned in the airway and oesophagus. Optical coherence tomography is used to take calibrated cross-sectional images of the airway lumen as the ... (Read Full Article)
