Abstract:
A method for ultrasonically imaging a region of the body which has been infused with a microbubble ultrasonic contrast agent comprising the steps of:transmitting a first pulse into the body which is focused at a first focal point within the body to cause a response from microbubbles located over a first range of depths;receiving echoes following the transmission of said first pulse;transmitting a second pulse into the body which is focused at a second focal point within the body different from the first pulse to cause a response from microbubbles located over a range of depths corresponding at least partially to the first range;receiving echoes following the transmission of said second pulse; andcorresponding echoes received in response to the first and second pulses to produce an ultrasonic image of the contrast agent.
