Patent ID: 6942617

Claim:
A stone-tracking system comprising: a servo-motion unit comprising a motion platform including an arc track, a shock-wave reflector being mounted on the arc track; an ultrasound scanner comprising an ultrasound scanning probe mounted on the motion platform for localizing a position of a patient's stone at any instant and generating information of stone position; a motion controller connected to the servo-motion unit for controlling the servo-motion unit; and a data processing unit connected to the ultrasound scanner and the motion controller, the data processing unit receiving the information indicative of stone position from the ultrasound scanner and automatically actuating the motion controller in adaptive manner responsive to the information indicative of stone position to cause relative movement between the motion platform and a bed on which the patient lies until a focus of the shock-wave reflector is coincident with the stone position, the data processing unit including a moving-mechanism control program that controls the motion of the motion platform to move in accordance with a displacement of a patient's stone.
