  • Vector doppler medical devices for blood velocity studies
    Patent number: 5409010
    Abstract: An ultrasonic pulse-echo medical device for determining the angular heading and magnitude of the velocity of blood flowing through a blood vessel by transmitting a pulsed ultrasonic beam from a single transmitting transducer and receiving echoes from sample volumes along such beam by a plurality of ultrasound receiving transducers. Independent motions in the same sample volume, such as those of a moving vessel wall and the motion of blood flowing through the blood vessel, can be separately analyzed and displayed.
