Abstract: A therapy system for treatment of a subject with focused acoustic waves has a source of focused acoustic waves, equipment for displacing the focus none of the focused acoustic waves and the subject to be treated relative to one another, and a locating system which non-invasively acquires the three-dimensional spatial position of a region within the subject to be charged with the focused acoustic waves relative to the focus zone of the focused acoustic waves continuously as a function of time. The system further includes a display which graphically displays the three-dimensional data generated by the locating system.

Abstract: An acoustic lens for the transformation of a planar wave into a spherical segment-shaped wave, and vice versa, is disclosed. In order to avoid aberrations, the lens is fashioned rotationally symmetrical relative to its center axis and biconcavely, the lens surface adjoining the medium in which the planar wave propagates is produced by the rotation of a section of a straight line, the lens surface adjoining the medium in which the spherical segment-shaped wave propagates is produced by the rotation of a section of an ellipse, and the angle between the straight line and the center axis as well as the angle between the major half-axis of the ellipse and the center axis are selected such that a planar or spherical segment-shaped wave entering into the lens propagates in the lens as a conical wave whose aperture angle is equal to double the angle at which the minor half-axis of the ellipse intersects the center axis.

Abstract: The present invention is directed to a method and apparatus for acoustic irradiation of a pathological change in a patient comprising a housing containing a shock wave generator positioned in a fluid-filled focusing chamber closed by a membrane characterized by a ring of elastic material being secured to the housing and surrounding the membrane and projecting beyond the membrane while in an idle position. The ring is provided with a channel system to allow evacuation of air from the space between the ring, membrane and the skin of the patient and also for introducing a coupling fluid into this space. The housing includes a channel for introducing additional fluid into the fluid-filled focusing chamber to cause the membrane to be expanded into the space and to engage the skin of the patient with a thin film of the coupling fluid disposed therebetween.

Abstract: A shockwave generator for extracorporeal lithotripsy has a housing filled with an acoustic propagation medium, through which shockwaves propagate, and in which an ultrasound applicator is disposed for locating a calculus to be treated. The ultrasound applicator has components which may be damaged if traversed by shockwaves. At least a portion of the ultrasound applicator in which these components are disposed is therefore acoustically shielded with a substance having an acoustic impedance substantially differing from the acoustic impedance of the propagation medium, so that essential parts of the shockwaves are reflected thereby and thus the non-reflected parts do not reach the shielded portion of the ultrasound applicator with sufficient energy to damage the compartments.

Abstract: An ultrasound generator for acoustic irradiation of pathological changes of a human body comprises a planarly fashioned piezo-electric transducer which is acoustically coupled to an acoustical lens on one surface by a soft metal layer and is acoustically coupled on the opposite surface by a second soft metal layer to a dampening member. The soft metal layers act as both acoustically coupling layers and as electrodes for the piezo-electric transducer. The piezo-electric transducer can be formed of either a plurality of layers which are spaced apart by soft metal layers acting as electrodes, a single piezo-electric plate, or a plurality of plates arranged side by side in the same plane.
