Abstract: A shock wave and/or ultrasound therapy system includes an ultra-sound and/or shockwave source suspended on a hexapod drive and an X-ray system. A system controller configured to generate control signals for the hexapod drive to align the ultrasound and/or shockwave source with the X-ray system based on the displacement of a known object between two images taken at different tilt angles of the X-ray system.

Abstract: A device for treating the human or animal brain with shockwaves has a shockwave transducer coupled to a position sensor for detecting the position of the shockwave transducer. The device is adapted to evaluate the signals of the position sensor to calculate the position of the focus spot of the shockwave transducer. Furthermore, a mapping device is provided for mapping the movement of the focus spot over a plurality of positions together with the applied shockwave dose at each of the positions. The applied shockwave dose may be indicated on a color display.

Abstract: A piezoelectric shock wave generator for use in medical equipment includes a plurality of piezoelectric elements being electrically interconnected to operate in parallel and mounted on a common carrier of curved configuration; a coupler medium couples shock waves as generated by these piezoelectric generators into the body of a living being, the improvement includes electrical insulation between the piezoelements being in fluid, i.e. liquid or gaseous state, in that each piezoelectric element is surrounded by the fluid in any direction towards any other piezoelectric element; the front ends of the piezoelectric elements may be physically separated, so that the coupler fluid and the isolating fluid are the same, and having a common flow space; alternatively, a membrane in front of all said piezoelectric elements provides electrical interconnection between them and physically separates the isolating fluid from the coupler liquid.

Abstract: In extracorporal lithotripsy a shock wave that is focussed on a concrement is followed by a pain producing pressure wave. This wave is filtered by means of a membrane bulging inwardly into the focussing chamber, closing the same and having a thickness smaller than the predominant wave length of the shock wave.
