Ultrasound data is acquired by a synthetic aperture technique which uses multiple ultrasound transmissions from point sources. RF data is stored and processed. Doppler velocities for pixels in an insonified region are obtained by processing the stored data. One or more pan boxes may be provided. Doppler velocities may be determined by obtaining I and Q images for a plurality of frames and performing autocorrelation across the frames for some or all pixels in the frames.

By using a structured vocabulary where subsets of a total large vocabulary are used for speech recognition to control an ultrasound machine, recognition performance is improved. Where the subsets of voice commands are selected to fit the state of the ultrasound machine so as to afford complete control of the machine, little or no degradation of the control of the machine will result. A two-way communication link between the voice control system and the ultrasound machine permits the monitoring of the state of the ultrasound machine so that subsets of the total vocabulary may be made active. From knowledge of the state of the ultrasound machine, dynamic macros may be implemented for streamlined control of the ultrasound machine. A two-way communication link between the voice control system and the ultrasound machine permits simultaneous control by means of, but not limited to, voice control, keyboard and foot-switch.
