Lithotripsy ellipse
WebIn medical lithotripsy, this principle is used to treat kidney stones. A patient is placed in an elliptical (really ellipsoidal) room which perfectly reflects sound waves. They are carefully placed so that their kidney stone is located precisely at focal point F2. Meanwhile, a powerful device emits ultrasonic shock waves at point F1. WebThe reflective property of an ellipse is used in lithotripsy. Lithotripsy is a technique for treating kidney stones without surgery. Instead, high-energy shock waves are emitted from one focus of an elliptical shell and reflected painlessly to a patient's kidney stone located at the other focus.
