Figure 4 Individualized, 3D deterministic model of the conducting part of the human tracheo-bronchial tree.
Notes: For clarity, the branching structure is only shown in the right and left upper lobes. A complete lung structure model will allow for accurate determination of the pulse arrival time at each individual acinus.
