Particle Image Velocimetry to Evaluate Pulse Wave Velocity in Aorta Phantom with the lnD –U Method

ConclusionThe PIV technique PWV measurement showed good agreement with the direct tensile test method with a 5.6% difference in Young ’s modulus. Considering the uncertainties from the two methods, the measured elasticities are consistent and close to a 50–60 years old male aortic behavior. The choice of silicone for the phantom material is a relevant and promising option to mimic the human aorta onin vitro systems.
