Abstract
This report summarizes our experiments with novel ultrasound phantoms that mimic essential biomechanical and dynamical vascular features of soft biological tissues. Real-time RF echo acquisition using a Siemens Elegra ultrasound system at 7.5 MHz provided a time series of ultrasonic images that were used to image longitudinal strain from pulsed and steady flows. Physical features of internal deformation patterns resulting from pulsatile flows revealed that ultrasonic strain imaging could be a very sensitive method for observing important properties related to physiological fluid flow.
