SYSTEM FOR THE ABLATION OR THE MONITORING OF A ZONE OF THE HEART BY ULTRASOUNDS AND ASSOCIATED METHODS

摘要

The invention relates to a system for the ablation or the monitoring of a zone of the heart by ultrasounds, comprising: a means for measuring the electrical activity of the heart in order to acquire an electrocardiogram (ECG); a phased array for generating a beam of focussed ultrasound signals (Fus) on at least one targeted zone (Zc) of the heart; an imaging system determining an image of a transcostal wall projected in an image plane of the phased array (RES_US) by taking into consideration the position and the direction of the phased array and making it possible to deactivate elements of the phased array in accordance with the position of said elements with regard to the position of the projected image of the transcostal wall; a positioning system coupled with the phased array (RES_US) so as to control the position of at least one focussed zone of at least one beam of focussed ultrasound signals (Fus) on the position of the at least one targeted zone (Zc), a monitoring system capable of measuring a temperature and a tissue deformation in the targeted zone (Zc); and a device for measuring a level of cavitation in the targeted zone.
