Method and device for locating and destroying an anatomical anomaly by means of elastic waves, with tracking of the target and automatic triggering of the shots

摘要

Device for locating and treating an anatomical target, comprising the periodic emission 1 of a fixed, focused beam of elastic treatment waves, the formation in real time of an echographic image of the target between the emissions during the period of treatment, by means of an auxiliary ultrasonic beam 2 which executes a sweep substantially centred in a plane of symmetry of the fixed beam, the displaying on the display support 4 of the images of a marker representing the theoretical position of the focus of the fixed beam, and the integral movement of the emission sources of the beam until the marker coincides with the image of the target, characterised by the selection 3-15 if the echoes forming the image of the target on the basis of the coordinates of the region of impact of the echographic beam with respect to the echographic source, by slaving 21-23 the said movement on the basis of signals derived from the selected echoes, until the said coincidence is achieved, and by the automatic triggering 1001 of the shots when this coincidence occurs.
