Unit 556 Therapeutic Applications
of Ultrasound

Sonolith®

In the past, researchers from our unit helped develop technology for various models of lithotriptors produced by EDAP TMS S.A. Sonolith® 2000, Sonolith 3000, Sonolith 4000, and the Sonolith Praktis are all examples of successful technology transfers from our research. These machines utilize both piezoelectric and electroconductive technologies.

Presently, research in extracorporeal shock wave lithotripsy (ESWL) is continuing within the unit, with the goal of producing smaller and more efficient piezoelectric generators. ESWL is a noninvasive procedure using sophisticated technology that combines X-ray imaging, ultrasound, and acoustic shock wave production to diagnose and disintegrate renal and urinary stones. Researchers from Team 1, primarily, are engaged in this work and student theses recently completed give a general description of the type of work being done.
