Fig. 18From: A deformable template method for describing and averaging the anatomical variation of the human nasal cavityComponent-specific cross-sectional areas. Measurements of cross-sectional areas of the left (downward triangles) and right (upward triangles) passageways for the mean geometry (solid line). The variation of measurements of patient geometries are shown as transparent filled areas (black=inferior, green=middle, blue=superior), representing one standard deviation (in both the upward and downward direction) from the meanBack to article page
