Abstract

L'invention concerne un dispositif d'insonification (1) d'un milieu, apte à générer un faisceau d'ondes focalisées autour d'un point d'une zone dite de focalisation utile pour l'imagerie du milieu ou la modification de propriétés du milieu, le dispositif d'insonification (1) comportant une structure porteuse intrinsèque ou extrinsèque sur laquelle est installé un réseau d'un nombre prédéfini de transducteurs ultrasonores (12) aptes à être commandés indépendamment pour la génération du faisceau d'ondes focalisé.Selon l'invention, les transducteurs (12) servant pour la génération du faisceau d'ondes focalisé sont situés le long d'au moins une spirale (11) enroulée sur une surface tridimensionnelle concave (10) dont la forme et la taille sont choisies pour permettre une focalisation optimale du faisceau à une longueur focale prédéterminée et dont la concavité est tournée vers la zone de focalisation
