Abstract: An ultrasonic image scanning system for scanning an organic object includes a container for containing a coupling medium for transmitting an ultrasonic signal to the organic object disposed therein whereby a simultaneous multiple direction scanning process may be carried out without physically contacting the organic object. The ultrasonic image scanning system further includes ultrasound transducers for transmitting the ultrasonic signal to the organic object through the coupling medium without asserting an image deforming pressure to the organic object. These transducers distributed substantially around a two-dimensional perimeter of the container and substantially at symmetrical angular positions at approximately equal divisions of 360 degrees over a two-dimensional perimeter of the container. The transducers are further movable over a vertical direction alone sidewalls of the container for a real time three dimensional (3D) image data acquisition. The container further includes sidewalls covered with a baffle layer for reducing an acoustic reverberation.

Abstract: A method and system for using two-dimensional transducer arrays for improving the field of view during an ultrasonic examination are disclosed. The ultrasonic imaging system includes a two-dimensional transducer array with a plurality of acoustic elements, a beam controller, a signal processor, and a display. The beam controller controls a generated acoustic beam capable of being advanced longitudinally or laterally along the two-dimensional transducer array. Additionally, the generated acoustic beam is capable of being phase-shifted by the beam controller. Combining the phase shifting of and advancement of the acoustic beam increases the field of view of the two-dimensional array.

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.
