Correlation between two back sides.

Correlation between the left and the right side of the normalized back side radii of the 2D transverse cross-section of the torso, (a) from healthy control, (b) and (c) from the patient at the time of her first scan and during a follow-up examination respectively. Black circles are the extracted original scattered points from the contour, blue circles indicate the ideal (symmetrical) shape. The linear trend of the transverse section has: a black line indicating the original shape, and a blue line indicating the ideal symmetric shape. The insets show the corresponding transverse cross-sections. Indicated are also the values of R2, that characterize the asymmetry of the backside torso contour shown here.
