Flow phantom model. The pulsatile pump, set to 120 beats/minute and a net flow of 0.75 liters/minute, was connected to the “common inlet,” which was connected to the ascending aorta (Aao). The three outlets on the aortic arch correspond to the aortic arch vessels in patients: (1) the brachiocephalic artery (BA), (2) the left carotid artery (LCA), and (3) left subclavian artery (LSA). The three aortic arch vessels and the descending aorta (DAo) then merge into a “common outlet” that was returned to the pump. The common inlet (ascending aorta), the descending aorta and the three aortic arch vessels at the aortic arch were arranged in parallel so that a single 2D flow measurement with high spatial resolution could be acquired in a reference plane to measure flow in all branches simultaneously. The total flow rate was verified using timer and beaker at the common outlet. (a) Flow phantom 3D model; (b) inlet flow curve; (c) flow imaging in reference plane.
