Abstract
There is provided a method of improving a measurement of the flow velocity of blood in a blood vessel of a subject, the method comprising using an ultrasound transducer to emit an ultrasound beam to measure flow velocity in a part of a body of a subject; forming a spatial time velocity profile for the part of the body from the measured flow velocity; and analyzing the spatial time velocity profile to determine a correction to the angle of the ultrasound beam with respect to the subject, the correction being based on a difference between the position of a peak in the spatial time velocity profile and the center of the spatial time velocity profile.
