ABSTRACT:
Ultrasound energy has been observed to rapidly destroy a large quantity of microbubbles. The duration and intensity of the contrast effect is greatly diminished by conventional imaging frame rates and power levels. Altering the imaging sequence by strategically shooting ultrasound image frames at various transmit powers and reducing the number of transmit lines per frame allows for enhancement of the contrast effect (increasing maximum intensity and duration).
