Abstract[English]
In an ultrasound system, echo focusing is performed to align ultrasound pulse peaks, establishing the phase delay required for each ultrasound transducer element, and the temporal displacements among pulses are determined using, for example, time-of-flight (ToF) measurements. The combined approach aligns the phases and the envelopes of pulses delivered by the active transducer elements that contribute energy during treatment. Moreover, it permits long pulses to be used for phase alignment in the preparatory stage and perfectly aligned short pulses in the sonication stage.[French]
Dans un système à ultrasons, la focalisation d'écho est effectuée pour aligner des pics d'impulsion ultrasonore, établir le retard de phase requis pour chaque élément de transducteur ultrasonore, et les déplacements temporels entre les impulsions sont déterminés à l'aide, par exemple, de mesures de temps de vol (ToF). L'approche combinée aligne les phases et les enveloppes d'impulsions délivrées par les éléments transducteurs actifs qui contribuent à l'énergie pendant le traitement. De plus, elle permet d'utiliser des impulsions longues pour un alignement de phase dans l'étape préparatoire et des impulsions courtes parfaitement alignées dans l'étape de sonication.
