Abstract
A method and apparatus of operating an ultrasound imaging apparatus so as to obtain continuous wave (CW) Doppler data from a user selected area comprises operating a multiple element transducer array and its associated delay and signal processing circuitry so as to develop and display in substantially real-time a two-dimensional ultrasound image, operating a user controllable device so as to cause a display of at least one controllable position marker in substantially real-time within the displayed two-dimensional ultrasound image, which marker selects an area of sensitivity within the ultrasound image for which it is desired to obtain CW Doppler data, operating the multiple element transducer array and its associated delay signal processing circuitry based upon the position of the selected area so that,
