Zusammenfassung:	The invention relates to a phased-network ultrasound transducer for medical use, comprising a single support (2) and a group of transducer elements (3) distributed randomly on the surface of the support (2), said transducer elements (3) being fixed. According to the invention, the group comprises at least two sub-groups of transducer elements (3), each of said sub-groups having a different geometric point of convergence such as to focus an ultrasound energy in a different coverage volume (4, 5) such that the arrangement of said coverage volumes covers a target volume to be treated. In addition, the invention includes control means for controlling the transducer elements (3) independently of one another. L'invention concerne un transducteur d'ultrasons en réseau phasé à usage médical, ledit transducteur comprenant un support (2) unique et un ensemble d'éléments transducteurs (3) distribués de manière aléatoire à la surface dudit support (2), lesdits éléments transducteurs (3) étant fixes. Selon l'invention, - ledit ensemble comporte au moins deux sous-ensembles d'éléments transducteurs (3), chacun desdits sous-ensembles d'éléments transducteurs (3) ayant un point de convergence géométrique distinct de manière à focaliser une énergie ultrasonore dans un volume de couverture (4, 5) distinct de sorte que l'arrangement desdits volumes de couverture couvre un volume cible à traiter, et - des moyens de pilotage pour piloter lesdits éléments transducteurs (3) indépendamment les uns des autres.
