This model is like as follows:
a segment of lung tissue was modeled as an array of randomly positioned
hollowed spheres (simulating alveoli). A 1*1*11.6 mm3 volume was created to match the thickest lung region (11.6 mm), with simulated alveoli given a 75% packing fraction and a Gaussian distribution of diameters. A mean diameter of 60 μm with a standard deviation of 10 μm was used to match the known size distribution of 38–80 μm .

Thank you so much.
Liu
