Lithotripsy is a noninvasive medical procedure that is used to break u kidney stones in the body. A machine uses the foci properties of an e concentrate shock waves generated at one focus on a kidney stone lo the other focus. a. If the major axis is 44.6 cm and the minor axis is 29 cm, how far very back of the reflector should a kidney stone be located for the result? b. Placing the coordinate axes so that the center of the ellipse is at tl ellinse that can be used to model the reflector?

Question
5) Lithotripsy is a noninvasive medical procedure that is used to break up
kidney stones in the body. A machine uses the foci properties of an ellipse to
concentrate shock waves generated at one focus on a kidney stone located at
the other focus.
а.
If the major axis is 44.6 cm and the minor axis is 29 cm, how far from the
very back of the reflector should a kidney stone be located for the best
result?
b. Placing the coordinate axes so that the center of the ellipse is at the origin, what is an equation for the
ellipse that can be used to model the reflector?
kidney stone at focal point F,
ellipsoidal
reflector
water cushion
spark gap electrode
at focal point F,
