   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 ...

5. 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)

6. A Method Of Providing Quantitative Information About The Lower Airways Of A Lung (Wo 2009/059368)

   Explore Article wipo.int (May 14 2009) Bronchoscopy , Patents

   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. ...
