Abstract

Technique de traitement de tissus (136) par des ultrasons focalisés. On place à proximité du tissu (136) à traiter un réflecteur d'ultrasons ou un convertisseur d'énergie ultrasonore (128) qui transforme l'énergie ultrasonore reçue en chaleur, stocke cette chaleur puis la libère avec le temps dans le tissu (136) à traiter. On oriente ensuite un transducteur d'ultrasons (120) en situant son foyer (142) à proximité du réflecteur ou du convertisseur d'énergie ultrasonore (128). On dirige alors sur le tissu (136) les ultrasons focalisés à haute intensité pendant que le réflecteur ou le convertisseur d'énergie ultrasonore (128) est en place.
