Abstract
A tracking system for stone treatment by extracorporeal shock wave lithotripsy includes a data processing unit, a motion controller, a servo-moving platform, a stone image-processing module, a stone localization module, and a moving-mechanism control module. With the use of the stone-tracking system, the performance of an extracorporeal shock wave lithotriptor can be greatly improved, resulting in less side effect such as tissue damage.
Claims10
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 sending 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 of the stone position from the ultrasound scanner and sending a signal to the motion controller in response to the information of the 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.
