The ability to measure multi-component velocity vectors in opaque flows, especially in blood flows, would have a number of important benefits. Over the last few years, we have developed a new technique, echo particle imaging velocimetry (echo PIV), based on the synthesis of two technologies: PIV and digital brightness-mode (B-mode) ultrasound contrast imaging. Recently-reported results using a custom-developed Echo PIV system [1] showed the utility of this technique in accurately measuring two-dimensional velocity vectors in a variety of opaque flows.
