Abstract
In a shockwave generating apparatus, a shockwave effective region pattern is displayed on a B-mode ultrasonic tomographic image of a biological body under superimposition state. The shockwave generating apparatus includes: an imaging cata acquistion unit for imaging an interior area of a biological body under medical examination, containing an object to be removed, thereby to produce image data on the interior area; a shockwave generator for generating shockwaves to be focused onto the object to be destroyed; a position detecting means for detector a focus position of the shockwaves in relation with an image of the interior area so as to obtain positional information on the focus position; an image memory for storing therein data on a shockwave effective region produced by receiving the shockwaves having a predetermined physical value, in which region damage caused by the shockwaves having a predetermined physical value is done to the biological body; and a display units for displaying the image of the interior area based on the image data and a pattern indicative of at least the shockwave effective region based on both the focus position information and the shockwave effective reg…
