Scatter plot of percentage body fat estimated by 3-dimensional photonic image scanning (3DPS) and underwater weighing (UWW) in 63 human subjects [30 normal-weight subjects (8 children) and 33 obese subjects (5 children)]. For both methods, body volume was measured at the end of a maximum expiration and was corrected for residual lung volume, which was measured independently by spirometry. The following equation was obtained by linear regression: y = 0.8599x + 3.4012 (r2 = 0.6544, SEE = 7.948%).
