2. Distribution of airway narrowing responses across generations and at branching points, assessed in vitro by anatomical optical coherence tomography

   Explore Article Respiratory Research (Jan 23 2010) Bronchoscopy

   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)

3. Airway Narrowing Assessed by Anatomical Optical Coherence Tomography In Vitro: Dynamic Airway Wall Morphology and Function

   Explore Article Journal of Applied Physiology (Nov 13 2009) Bronchoscopy

   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 ...

4. In vivo 4D imaging of the human lower airway using anatomical optical coherence tomography

   Explore Article SPIE Digital Library (Oct 5 2009) Endoscopy

   Anatomical optical coherence tomography (aOCT) is a long-range, fibre-optic endoscopic imaging modality capable of quantifying the size and shape of the human airway lumen. This paper presents the first application of respiratory gating to 3D aOCT volumetric data. A sequence of time-gated data volumes are generated, characterising the dynamic behaviour of a segment of the lower airway over an averaged respiratory cycle. The technique is demonstrated on in vivo data ... (Read Full Article)

6. Measuring airway dimensions during bronchoscopy using anatomical optical coherence tomography

   Explore Article European Respiratory Journal (Jun 21 2009) Otolaryngology

   Airway dimensions are difficult to quantify bronchoscopically because of optical distortion and a limited ability to gauge depth. Anatomical optical coherence tomography (aOCT), a novel imaging technique, may overcome these limitations. This study evaluated the accuracy of aOCT against existing techniques in phantom, excised pig and in vivo human airways. Three comparative studies were performed: (i) micrometer-derived area measurements in ten plastic tubes were compared to aOCT-derived area; (ii) aOCT-derived ... (Read Full Article)

   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. ...
