Process and device of an anatomic anomaly by means of elastic waves, with tracking of the target and automatic triggering of the shootings

摘要

A Process and device of location and destruction of an anatomic target includes the periodic emission of a focused treatment beam of elastic waves and an echographic image of the target formed in real time during the treatment period by means of an ultrasonic auxiliary beam carrying out a scanning substantially centered in a symmetry plane of the focused treatment beam. Also displayed superimposed on the target image is a mark showing the theoretical position of the focal point of the treatment beam. Selection of the image forming echoes reflected from the target as a function of the coordinates of the region of impact of the auxiliary beam with respect to the echographic source is effected and the treatment and auxiliary sources are simultaneously displaced under the control of signals derived from the selected echoes until the coincidence between the image of the mark and the image of the target object is reached where the treatment beam emission is then triggered.
