Abstract

L'invention concerne un appareil de sonde ultrasonore pour ultrasons focalisés guidés par résonance magnétique, comprenant un support de sonde (1), une tige de liaison de sonde (2) et une pluralité d'unités de sonde (3). La tige de liaison de sonde (2) est reliée à une extrémité axiale du support de sonde (1). Chaque unité de sonde (3) est pourvue d'une surface de focalisation (31) configurée pour former un point focal ultrasonore. Au moins une unité de sonde (3) a une profondeur focale ultrasonore différente de celles des autres unités de sonde (3). La pluralité d'unités de sonde (3) sont montées sur le support de sonde (1), de telle sorte que les surfaces de focalisation (31) de celles-ci sont réparties sur la surface latérale circonférentielle du support de sonde (1). L'appareil de sonde ultrasonore intègre la pluralité d'unités de sonde (3) pour permettre de multiples profondeurs focales ultrasonores sur un seul appareil, ce qui permet d'obtenir l'ablation de multiples lésions dans différentes zones avec le guidage d'une seule imagerie par résonance magnétique, de réduire la période de traitement d'un patient, et d'améliorer considérablement l'efficacité.
