SYSTEM AND METHOD FOR SENSING AND LOCATING DISTURBANCES IN AN ENERGY PATH OF A FOCUSED ULTRASOUND SYSTEM

摘要

A method for sensing a disturbance in a transmission path of a converging ultrasound energy beam transmitted by a transducer in a docussed lutrasound system comprises transmitting a burst of ultrasound energy from the transducer, detecting whether a reflected portion of the ultrasound energgy burst is received at the tranducer within a certain time period following transmission of the burst, and, if so, analyzing the received reflected portion to determine a characteristic of the disturbance.
