Abstract:
1. A Doppler ultrasound system, comprising: an ultrasound transducer operable to emit ultrasound signals into the subject along an ultrasound beam axis; an ultrasound receiver for detecting echo signals resulting from the ultrasound signals emitted into the subject; an analog-to-digital converter (ADC) circuit coupled to the ultrasound receiver to quantize the echo signals received by the ultrasound receiver into digital sample values; and a processor coupled to the ADC circuit and operable to process the digital sample values and to calculate Doppler shift signals as a function of time for a plurality of locations along the ultrasound beam axis and to further calculate detected Doppler signal power data as a function of time and associate the detected Doppler signal power data to the Doppler shift signals for the plurality of locations along the ultrasound beam axis, the Doppler shift signals representative of blood flow detected along the ultrasound beam axis as a function of time.
