   Lithotripsy partially immerses the patient in a warm solution of
   specific density. Then, beams of ultrasound traveling through the
   liquid and tissues ultimately interfere at selected foci.  Resonance
   effects occur in obstructive bodies, causing fractures.
   I think I saw a story about this on tv news (?) and heard a loud
   sound at intervals of less than a second. It sounding kind of like
   the crack of a whip.
