What is described here is a method of and a device for visualizing the orientation of therapeutic sound waves onto a region to be treated or processed, respectively, using a display unit including a screen on which the orientation of said therapeutic sound waves is symbolically displayed with respect to the region to be treated. The invention excels itself by the provision that the sound wave source and the region in space, through which the sound waves are propagating, as well as the region to be treated or processed (hereinafter referred to as treatment site) are perspectively displayed on said screen by allocation of physical figures, and that the perspective view varies with the correct movement when the site or the orientation of the sound wave source and/or the treatment site and/or the site or the orientation of the screen is varied.

1. Field of the Invention
The present invention relates to a method of visualising the orientation of therapeutic sound waves onto an area to be treated or processed, as well as to a device for carrying through this method.
2. Prior Art
The invention will be described in the following by exemplary embodiments, without any restriction of the general inventive idea, referring to the drawing which explicit reference is made to in all other respects as far as the disclosure of all inventive details is concerned which are not explained in more details in the text. In the drawing:
FIG. 1 illustrates the distribution of the sound pressure through an opened cone;
FIG. 2 represents a treatment scenario into which an X-ray C arc has been mixed for an explanation of the possible inputs for the user site;
FIG. 1 shows how the distribution of the sound pressure is represented by an opened cone 1. The reference numeral 2 identifies the region onto which the sound field is to be oriented and which is to be caused “to coincide” with the sound wave focus not illustrated in this figure.
In this representation the imagination of the entry cone is made use of, which is mostly imagined by the user. The cone envelope corresponds to the transition between the focussed wave and the marginal diffracted wave, thus representing, in a first approximation, the region in space within which a therapeutically effective sonic energy is transmitted.
The discontinuity of the cone envelope serves to prevent the treatment site 2 from being covered. Another possibility to the same end consists in the semi-transparent representation of the cone (“rendering” in the “transparent mode”).
