Abstract
An ultrasonic imaging system uses first and second perpendicular arrays. The first array is operated at high power to selectively destroy contrast agent suspended in flowing blood in discrete regions. The second array 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.
