High frame rate flow imaging using plain wave transmits: A feasibility study

Ultrafast imaging using plane wave excitation has been recently introduced for high frame rate color flow imaging. In this paper, we will propose a frequency-based analysis method to estimate the average, minimum, and maximum flow velocity from the ultrafast images. The result has been compared with the traditional color flow imaging and showed high consistency. We believe the proposed high frame rate color flow imaging method will be useful when studying the complex, fast changing flow patterns, and turbulent flow.
