The invention relates to a method which comprises emitting ultrasound into a liquid mixture containing first and second reagents in separate phases initially separated by a liquid precursor-gas barrier, the ultrasound having a high enough energy level to vaporize the precursor gas, such as to contact the reagents and thus to activate a chemical reaction therebetween.

Method for activating a chemical reaction, solution that can be activated by said method and device for implementing said method

A method of high-resolution ultrasound imaging, in which transducers are made to emit ultrasound waves in a field of observations containing micro bubbles, by making the micro bubbles burst one by one in tandem with the emissions of ultrasound waves. At each shot j of an ultrasound wave, raw reverberated signals S(i,t) picked up by each transducer i are recorded, and then differential signals V(i,t) representative of variations between successive raw signals are determined, a parabolic function P(x) is fitted to the differential signals corresponding to each shot j, and then a crest A(x,y) of this function P, corresponding to the position of the micro bubble destroyed between shots j&#x2212;1 and j, is determined.
