<p>The device has a focused shock wave generator, an ultrasonic transmitter/receiver unit with an ultrasonic transducer and an evaluation unit for evaluating received reflected ultrasonic waves. The transducer emits pulses waves and the evaluation unit determines a coefficient of the time correlation between reflected ultrasonic waves associated with successively emitted pulses and output an associated correlation coefficient signal. The lithotripter (10) has a focused shock wave generator (16), an ultrasonic transmitter/receiver unit with an ultrasonic transducer (24) for emitting ultrasonic waves into the body (12) and receiving waves reflected from a target area and an evaluation unit for evaluating the received ultrasonic waves. The transducer is configured to emit pulses waves and the evaluation unit is configured to determine a coefficient of the time correlation between reflected ultrasonic waves associated with successively emitted pulses and output an associated correlation coefficient signal. AN Independent claim is also included for the following: (a) a method of monitoring fragmenting a target object, especially a stone, in an especially human body.</p> |
