Velocity vector fields and Turbulent Kinetic Energy (TKE) were acquired in an elastic and anatomically accurate replica of a human aorta equipped with a mechanical heart valve. Using the MRI acquisition of a multi-point velocity encoded sequence, velocities and TKE were computed with Bayesian parameter estimation. As a reference, both parameters were measured with Particle Tracking Velocimetry in the transparent setup. The comparison of both measurements shows good agreement for velocity and TKE values.
