Abstract
A therapy apparatus for treating a patient with focused acoustic waves has a source of focused acoustic waves which converge in a focus zone, and a locating system for locating a therapeutically relevant region of the body of the patient. The locating system has a graphic display for displaying an image of the therapeutically relevant region (S). The apparatus also includes control and circuitry mixing a properly scaled contour (C) of the focus zone within the respective image defining a boundary within which the acoustic waves do not fall below a threshold with respect to an acoustic characteristic. The controls can be used to set the size of the contour directly, or to set the size with respect to one or more selected acoustic parameters.
