1. A therapy apparatus comprising:

  • a source of therapeutic acoustic waves;

    a diagnostic ultrasound transducer which emits a diagnostic ultrasound beam directed at a subject to be treated, said diagnostic ultrasound beam having a central ray, and said diagnostic ultrasound transducer also receiving ultrasound waves reflected from said subject;

    means for operating said ultrasound transducer for displacing said central ray in a scan surface for scanning a body slice of said subject, said body slice having a middle surface corresponding to said scanning surface;

    means for generating and displaying a sequence of ultrasound images from the ultrasound waves received by said diagnostic ultrasound transducer; and

    adjustment means for, during the generation and display of said ultrasound images, continually displacing said scanning surface relative to said source of therapeutic acoustic waves for producing a maximum displacement of said scanning surface relative to a neural position of said scanning surface which does not substantially exceed twice an image resolution of said ultrasound images measured in a direction of the displacement of the scanning surface.
