Large or hard stones can be crushed with a mechanical lithotripter. |
Now a technique that uses laser light is about to enter clinical use, offering several potential advantages over the lithotripter. |
By the early 1990s, Fink's group and an industrial partner had developed a lithotripter with a time reversal mirror composed of 128 transducers. |
Now found in hospitals throughout the country, the lithotripter has radically changed the treatment of kidney stones. |
