Figure 1

The first row shows the WSS magnitude (WSS-M) in the entire thoracic aorta, obtained from a Phantom that simulates an aortic coarctation of 9 mm (A) and from one Volunteer (E). The WSS-M and OSI contour mean for each 2D cutting plane and standard across volunteers are depicted in B, F (AO1), C, G (AO2) D, H (AO3). It can be notice that the 3D and 2D WSS have the same shape distribution although the 2D WSS had in general larger values.
