Design outcomes

Primary

Measure	Time frame
To obtain blood flow boundary conditions from ascending aorta to internal and external iliac arteries, including branched arteries such as subclavian arteries, common carotid artery and visceral branch vessels. The main goal is to acquire volumetric flow rate, 4D velocity fields (i.e., 3D spatial coordinates and temporal points over the cardiac cycle), and 3D geometry of the entire aorta and its side branches in the aortic arch and abdomen FOVs.	—

Measure

Time frame

To obtain blood flow boundary conditions from ascending aorta to internal and external iliac arteries, including branched arteries such as subclavian arteries, common carotid artery and visceral branch vessels. The main goal is to acquire *volumetric flow rate*, *4D velocity fields (i.e., 3D spatial coordinates and temporal points over the cardiac cycle)*, and *3D geometry of the entire aorta and its side branches* in the aortic arch and abdomen FOVs.

Secondary

Measure	Time frame
Combining the obtained MRI data from aortic arch and abdomen regions, and reconstruct a general aortic segmentation.	—
