ABSTRACT:
The method for imaging vascular blood flow in a patient includes the steps of emitting ultrasound energy from a transducer with at least a portion of said ultrasound energy being reflected back towards the transducer, monitoring the reflected energy over time, calculating blood flow velocity in at least a portion of a patient's vascular system, filtering all velocities equal to or below the calculated or predetermined velocity to allow a high velocity locus to be defined, and producing a color Doppler flow map of the filtered velocity.
