ABSTRACT:
An ultrasound system is provided comprising an ultrasound probe having a 2D matrix of transducer elements transmitting a continuous wave (CW) Doppler transmit signal into an object of interest. The CW transmit signal includes a dither signal component and the probe receives ultrasound echo signals from the object in response to the CW transmit signal. The probe generates an analog CW receive signal based on the ultrasound echo signals. An analog to digital (A/D) converter converts the analog CW receive signal to a digital CW receive signal at a predetermined sampling frequency and a processor processes the digital CW receive signal in connection with CW Doppler imaging.
