Figure 3.

Developmental growth pilot data, ages 2 – 20, from in vivo CT scans. Hyoid landmarks were placed, and linear measurements taken as described in Table 1. Figure 3 displays the feasibility of using the segmentation and analysis methods presented to quantify growth using retrospective imaging studies. Despite variability in the growth trend of the different measurements, all variables show a rapid period of growth during the first few years of life with discrete differences in growth after about age 6–8 years, as well as male/females differences in growth.
