Wolfram Klosterhuber,Jörg Heiningnic waves as a therapeutic agent in medicine. Since there was, at that time, another kind of wave therapy, radiofrequency diathermy, already in use, why shouldn’t ultrasound come as an adjunct to it? Ultrasound had even an advantage over radio waves; it could be conveniently directed and accurately localized to the diseased area.

Wolfgang Meyerd images from holograms of long-wavelength, such as acoustical and microwave holograms. Since the wavelengthes are long in such waves, improvement of resolution is necessary, because the apertures of hologram planes are narrow compared with the optical holography, resulting in the low-quality reconstructed image.

Michael Weinhardt,Peter Jacobebbinghaus,Stefan Liebig metal tube and the transducer supporting arm protrudes from the narrow slot. The screw and tube are caused to rotate and may have a relative rotatory motion. The transducers both rotate in a horizontal plane and move vertically and thus trace out a helical path. Hence, a cylindrical space is ensonified having the helix as center.
