ABSTRACT:
A phased array sector scanning ultrasonic imaging system produces simultaneously, and samples, three receive beams for each transmitted ultrasonic pulse directed upon flowing reflectors. Flow velocity is measured in the cross range direction using a correlation technique while flow velocity in the range direction is simultaneously measured using a Doppler method. By performing cross correlation in both the range and cross range directions with data acquired from a set of such multi-beam acquisitions, a B-scan image is produced which indicates both magnitude and direction of the flowing reflectors.
