ULTRASONIC METHOD AND SYSTEM FOR IMAGING BLOOD FLOW

摘要

An ultrasonic imaging system (10) uses first (20), and second (22) perpendicular arrays. The first array (20) is operated at high-power to selectively destroy contrast agent suspended in flowing blood in discrete regions. The second array (22) is used to image the alternating bands of contrast agent depleted blood, and contrast image containing blood in order to allow blood flow characteristics to be assessed.
