43. A method for performing a therapeutic procedure using ultrasound, comprising:
-
detecting, at one or more detection locations, respective beacon signals coming from a beacon placed at a site in a body of a subject;
reversing each of the beacon signals with respect to a time-based property thereof, to obtain respective time-reversed ultrasound signals; and
generating the respective time-reversed ultrasound signals at each of the one or more locations. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79)
