ABSTRACT:
A calculi locator is provided having at least one ultrasound transducers in combination with a shock wave generator. The ultrasound transducer is rotatable about the longitudinal axis of a reflector of the shock wave generator. The shock wave generator includes a target focal point. The transducer is used to assure positional coincidence of the true location of the calculi and of the target focal point. Alternatively, either a mathematical correction unit is used or iterative measurements are used to correct for refraction errors in the location of the imaged calculi.
