1. A method for manufacturing a medical instrument, comprising:
fabricating an ultrasonic horn or concentrator having a predetermined shape and size;
operatively connecting an upstream or input portion of said horn or concentrator to an ultrasonic transducer assembly;
energizing said transducer assembly to generate at an input or upstream end of said horn or concentrator an ultrasonic calibration vibration having a desired motion pattern and desired frequency and amplitude characteristics;
automatically tracking movement of an operative tip of said horn or concentrator upon generation of said calibration vibration at said input or upstream end of said horn or concentrator;
automatically recording at least one signal encoding the tracked movement;
processing the recorded signal to generate a time reversal waveform; and
storing said time reversal waveform in a storage medium.
