1. A therapy apparatus for treatment with acoustic waves, comprising:

  • a source of acoustic waves and means for focusing said acoustic waves on a therapeutic effective region;

    displacement means for displacing the therapeutic effective region and a subject relative to one another;

    means for producing, at an arbitrary time and place, a first dataset identifying a spatial position of the therapeutic effective region and an orientation of the source relative to a first spatial coordinate system;

    means for producing, at an arbitrary time and place, a second dataset identifying a spatial position and an orientation of the subject relative to a second spatial coordinate system;

    display means for displaying, at an arbitrary time and place, an image of a portion of said subject, said portion containing a body region to be treated with the focused acoustic waves, and means for obtaining, on the basis of said image, a third dataset identifying a spatial position and orientation of said body region relative to a third spatial coordinate system;

    means for storing spatial position data identifying respective spatial positions of said first, second and third coordinate systems relative to each other; and

    means, supplied with said first, second and third datasets and with said spatial position data, for mixing a mark into said image, dependent on said first, second and third datasets and said spatial position data, indicating the position of said therapeutic effective region.
