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.

Methods and systems for ultrasound imaging

A method for determining a flow rate and/or a concentration of particles of a fluid flowing in a chamber, which includes the steps of: producing an ultrasound beam of a given frequency with a first transducer such that all fluid components traveling through an intersection region between the ultrasound beam and the chamber are insonated by the first transducer; receiving Doppler-shifted ultrasound signals generated by the fluid components in the insonated region of the chamber with a second transducer; acquiring the ultrasound signals received by the second transducer during an acquisition time; obtaining a Doppler Power Spectrum of the acquired ultrasound signals; and determining the flow rate and/or the concentration of particles of the fluid by adjustment between, on the one hand, the obtained Doppler Power Spectrum and, on the other hand, a model of the Doppler Power Spectrum.
