Abstract
There is provided a method for ultrasound imaging comprising applying an ultrasound modulation wave at a fixed frequency Fand a period Pto a target in a body, the body having received an injection of microbubbles through a fluid, the modulation wave causing the microbubbles to undergo stable acoustic cavitation, emitting, toward the target and concurrently with the modulation wave, ultrasound imaging pulses centered at a frequency Fand having a pulse repetition period of n*Pand a pulse delay of m*P/k, where the pulse delay varies with m, m<k, and k>1, detecting reflections of the ultrasound pulses by the microbubbles after each emission for a duration corresponding to a maximum depth of the target, and forming ultrasound images from the reflections.
