Abstract
A lithotripsy system capable of 3D tracking monitors the acoustic reflection from the stone in order to focus the shock wave on the stone regardless of shock wave displacement or stone movement. The tracking and focusing is based on a phased array concept, allowing the lithotripsy head to remain stationary and well coupled to the body. An alternate shock wave steering is based on refraction by a variable liquid wedge.
