Coaxial location for contact free comminution of concrements

摘要

A concrement in a human body is located by an X-ray system establishing an axis through the concrement; ultrasonic equipment determines a depth coordinate value for the concrement on that axis, and a shock gyrator and focusing system is placed on that established axis for obtaining the comminution. A rest is provided for placing the body in the action zone, and for establishing a second axis in a coordinate system; the third axis is perpendicular to the latter and defines locally the direction of position change for the various types of equipment needed to carry out the aforementioned program.
