From: Lung and fissure shape is associated with age in healthy never-smoking adults aged 20–90 years
Lung shape at ± 2.5 SD from the mean for each of the first four principal modes, for the size-inclusive (left column) and size-exclusive (right column) statistical shape models. The left main panel illustrates shape modes 1 to 4 for the size-inclusive model, and the right main panel for the size-exclusive model. The middle column shows the relative contribution of each mode as a percentage of the total population shape variance.
