Abstract: A method of detecting flow instability includes insonating an area of interest with ultrasound wave pulses, acquiring radio frequency (RF) data from echo pulses of the ultrasound wave pulses, processing the RF data, and deriving a Doppler band-width from the processed RF data by AR modeling. Also described herein is a device for detecting flow instability. The device includes an emitter configured to insonate ultrasound wave pulses on an area of interest, a receiver configured to acquiring radio frequency (RF) data from echo pulses of the ultrasound wave pulses, and a processor configured to process the RF data, and derive a Doppler band-width from the processed RF data by AR modeling.
