Applying anatomical optical coherence tomography to quantitative 3D imaging of the lower airway
MetadataShow full item record
Endoscopic treatment of lower airway pathologies requires accurate quantification of airway dimensions. We demonstrate the application of a real-time endoscopic optical coherence tomography system that can image lower airway anatomy and quantify airway lumen dimensions intra-operatively. Results demonstrate the ability to acquire 3D scans of airway anatomy and include comparison against a pre-operative X-ray CT. The paper also illustrates the capability of the system to assess the real-time dynamic changes within the airway that occur during respiration. © 2008 Optical Society of America.

Elastic properties of the central airways in obstructive lung diseases measured using anatomical optical coherence tomographyWilliamson, J.; McLaughlin, R.; Noffsinger, W.; James, A.; Baker, V.; Curatolo, A.; Armstrong, J.; Regli, A.; Shepherd, K.; Marks, G.; Sampson, D.; Hillman, D.; Eastwood, Peter (2011)Rationale: Our understanding of how airway remodeling affects regional airway elastic properties is limited due to technical difficulties in quantitatively measuring dynamic, in vivo airway dimensions. Such knowledge could ...
