Currently, an echo particle image velocimetry (ePIV) system for the investigation of in vivo blood flow and shear stress is under development at the University of Calgary. To date, encouraging preliminary results have been obtained when comparing ePIV derived velocities to analytical solutions. However, large discrepancies were noted between our steady state ePIV derived velocities and velocities measured using pulse wave Doppler (PWD). Ultrasound beam thickness, off axis centerline measurements and PWD angle of interrogation likely account for the differences observed.
