Abstract
A lithotripter has a source for focussed shockwaves and an X-ray device which is mounted for relative displacement and positioning in relation to that source of shockwaves; an improvement includes a device for aiming and sighting in cooperation with the X-ray equipment that includes a carrier element defining a first pair of X-ray contrasting aligned reference points and two additional X-ray contrasting reference points, on a second line and intersecting the first line at a point of intersection at about 15 to 45 degrees; and that aiming and sighting device is mounted in relation to said source of focussed shockwaves such that the point of intersection coincide with a focal point of the shockwave source.
