Echocardiography is the most available and safe method
to study hemodynamics parameters in patient with Aortic
Coarctations, however, is operator dependent, pressures
are over-estimated. Catheterization is the gold
standard, but is invasive, non-exempt of risk and
patient have to be exposed to x-ray. New methods need to
be developed to obtain hemodynamic parameters no
invasively, however developing these methods from
patient imaging data is difficult. In this work we have
built a realistic MR compatible thoracic aortic phantom
to simulate different grade of stenosis, which can be
used to validate hemodynamic parameters obtained from
PC- MRI data under controlled experiments.
