Abstract: In a method to generate a three-dimensional ultrasound image of a body region of a patient, spatially varying due to breathing motions, temporally successive B-images are generated with an ultrasonic transducer arrangement in a stationary image plane that, due to the breathing motion, pertain to various slice planes of the body region, and are combined dimensionally correctly with an image processing device into a 3D image.

Abstract: A bellows for coupling a source of acoustic waves having an acoustic propagation medium, to a patient, has a geometrical modification in that region wherein the bellows can be seated against the patient for the introduction of acoustic waves into the patient . The geometrical modification in the propagation path of the acoustic waves generated by the source of acoustic waves shapes the acoustic waves in a designated (designed) manner. Additionally or alternatively, the bellows can have a section in the region that is formed of a different material than the rest of the bellows.

Abstract: A shock wave source has a coil carrier, a coil, having a metallic membrane separated from the coil in insulating fashion for generating shock waves. The coil carrier is formed of a material that damps the formation and/or the propagation of audible acoustic waves in the generation of shock waves.

Abstract: A shock wave source has a coil carrier, having a longitudinal axis, a coil and a metallic membrane separated from the coil in insulating fashion for generating shock waves. The coil carrier has a generated surface, a first cover surface facing toward the coil and a second cover surface facing away from the coil. For reducing the low-frequency sound generation when generating shock waves, a cross-sectional area of the coil carrier intersected at a right angle by the longitudinal axis has a non-circular contour. A reduction of the audible sound generation when generating shock waves can also be achieved when the second cover surface of the coil carrier is non-flat.

Abstract: X-ray apparatus has a d.c.-a.c. converter circuit supplied with energy that is connected via a line connection to a high-voltage transformer supplying the high-frequency operating voltage to an X-ray tube. The line connection has a first and a second conductors that are insulated from one another and are disposed close to one another for achieving a low line inductance. These conductors have ratio of radius to conductor thickness such that a low ohmic impedance is established.
