Figure 1

A 3D profile of a porcine bronchial tree acquired by anatomical optical coherence tomography (aOCT). The major portion of the bronchial tree comprises a large parent bronchus that gives rise to smaller daughter bronchi (i.e., side branches) that branch off at an obtuse angle of departure. The figure shows the airway preparation in its relaxed state and after bronchoconstriction in response to carbachol.
