Abstract

Anatomic optical coherence tomography (aOCT) endoscopy, combined with intraluminal pressure measurement, can be used to quantify upper airway wall mechanical properties for treatment planning and monitoring in upper airway obstructive disorders. Using an anatomic aOCT endoscope with integrated pressure catheter to measure airway deformation as a function of pressure, two different mechanical models are explored for airway wall elastography: a local compliance model and an elastic spring model. The models are compared over the circumference of the airway. Results illustrate differences between local compliance, which focuses on the radial deformation, and the elastic spring model, which treats expansion along the circumference.
