ABSTRACT:
A method for making Doppler ultrasound measurements utilizes an ultrasound probe having two transducer arrays oriented at right angles to one another and spaced apart from one another. The first array is used to measure multiple apparent Doppler parameters such as velocity at respective regions within a cross section of a structure such as a blood vessel. The second array is used to measure second apparent Doppler parameters at one of these regions. The first and second apparent Doppler parameters for the same point are used to correct the first apparent Doppler parameters to more nearly equal true velocity or energy.
