    摘要: A system and method for detecting fluid flow. An ultrasound system comprises a signal generator providing ultrasound firing sequences applied to a linear array transducer. The transducer generating ultrasound energy applied to the fluid flow. A pre-processor comprises a digital RF data acquisition component receiving an RF signal from the transducer of back-scattered ultrasound energy and a B-mode image generation component for reconstructing images form the RF data. A post-processor executes particle image velocity (PIV) algorithms for generating velocity vectors indicative of the fluid flow. The sequences may have triangular waveforms.
