Abstract
Perfusion of tissue such as the myocardium by a microbubble contrast agent is imaged in realtime by a multiple pulse technique which uses low power transmit pulses which are sufficient to elicit a harmonic response from the microbubbles but are not high enough in power to cause substantial destruction to the microbubbles. In a preferred embodiment the realtime microbubble image sequence is displayed in color, overlaid with a grayscale image of the surrounding tissue in the region being imaged.
