The discrepancy between the actual unloaded geometry (UG) and the predicted unloaded geometry ($S_{\text{ug}}$) is quantified in terms of surface to surface distances of the AAA phantom inner wall surface. The latter is estimated at three different intraluminal pressure gauge readings and the distances assessed by the following metrics: Hausdorff ($D_H$), mean ($D_m$), and average RMS ($D_{\text{rms}}$) distances.

Distance metric (mm)	80 mm Hg	120 mm Hg	140 mm Hg
$D_H$	1.223	1.634	1.847
$D_H$ relative to maximum diameter (%)	(2.6)	(3.5)	(3.9)
$D_m$	0.380	0.642	0.764
$D_{\text{rms}}$	0.459	0.749	0.844
