文摘

Displacement distribution within airway wall estimated using image registration. Deformation of airway wall during pressure changes of breathing is heterogeneous. Medial layer of airway wall experiences highest strains during breathing. Airway narrows and stiffens heterogeneously in response to an agonist.
