The resulting sequence of signal samples is processed to obtain said velocity component.

摘要： A method for velocity estimation based on a complex demodulated doppler signal in a multi-gated doppler. The method is based on the autocorrelation function estimates of the complex demodulated doppler signal. Contribution to the correlation function from the receiver noise is found by measuring the noise in absence of echo signals. The obtained values are subtracted from the correlation estimates before further processing. A limited number of candidates for the true velocity are calculated from the autocorrelation function phase.

The series of pulses includes at least three pulses having three different amplitudes, respectively. The amplitudes are at least one of a positive non-zero voltage, a negative non-zero voltage, and an intermediate level voltage. The multi-level pulse sequence may be produced by a switch network having at least three different input voltage levels. The switch network outputs the multi-level pulse sequence at an output node to a transducer within a probe. Echo signals based on the series of pulses are received, and an ultrasound image is produced based on the received echo signals.

摘要： 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.
