The invention relates to a device for location and guidance by ultrasound. It consists of an echographic probe 1 fixed or sliding at the bottom of a spherical cap 2 representing a piezoelectric converter, the head of the probe being situated inside the cap. A second echographic probe 10 may be associated with the first 1, the second sweeping in a plane perpendicular to that of the first. This second probe is positioned as close to the target 3 as possible and it may move only in one plane, the plane of sweeping of the first probe, or alternatively perpendicular to this plane. The device according to the invention is in particular intended for location and guidance for an apparatus producing focused ultrasound for treatment. <IMAGE>
