Abstract
An extracorporeal isocentric lithotripter is presented having a common isocentric axis of rotation. The patient having a bodily concretion to be destroyed lies on a table which is movable to position the concretion on the isocentric axis. An X-ray emitter and an image intensifier lie on a common diameter which is rotated about said isocentric axis to position said X-ray apparatus and said image intensifier in at least two positions to ascertain the location of the concretion. A shockwave lithotripter shockhead is mounted on a support rotatable about said isocentric axis to align said shockhead with said bodily concretion. The shockhead is mounted on said rotatable support by a double pivot arrangement to bring the second focus point of said reflector into coincidence with said bodily concretion for destruction of said concretion.
