Abstract
Method and apparatus for developing an estimation of the velocity of a moving target, comprising, transmitting groups of pulse signals towards the target, receiving groups of echo signals caused by reflections of the transmitted groups of pulse signals from the target and spatially processing the echo signals for developing the estimation of the velocity of the target. In a preferred embodiment, the spatial processing is for only a single pair of adjacent ones of ultrasonic echo signals and the estimation developes a two dimensional image of blood flow velocities in the body of a patient.
