Abstract: Aspects of the technology described herein relate to automatically calculating an ultrasound pulse transmission direction and configuring an ultrasound device to transmit ultrasound pulses along the ultrasound pulse transmission direction for pulsed wave Doppler ultrasound imaging. Automatically calculating the ultrasound pulse transmission direction may be based on a selected sample volume within a subject where flow velocity is to be measured with the pulsed wave Doppler ultrasound imaging, and a selected direction of the flow velocity to be measured with the pulsed wave Doppler ultrasound imaging.
