Abstract
An apparatus for treating bone pathologies with acoustic waves includes a source of focused acoustic waves, a system for displacing the focus of the acoustic waves, and a system for locating the boundary surface between the bone to be treated and surrounding tissue. The locating system generates signals corresponding to the position of the boundary surface. A control unit, which operates the focused displacing system, is supplied with the signals identifying the position of the boundary surface, so that the focused displacing system is controlled to maintain the focus substantially at the boundary surface, independently of the position of the acoustic wave source.
