Definitions
- Electromagnetic shock wave generators may also be used such as the apparatus disclosed by Hahn et al. in U.S. Patent No. 4,655,220.
- piezoelectric Shockwave generators are equally well known to those skilled in the art and may also be used, such as the apparatus disclosed by Wurster et al. in U.S. Patent No. 4,821 ,730.
- These previously disclosed devices generate a distribution of high-intensity shock waves in a focal volume embracing the target concretions 4. It is well known in the art that the beam diameter of the shock wave pulses in the focal plane and the depth of focus along the shock wave axis are in the range of 2 to 15, and 12 to 120 mm, respectively.
- DORNIER HM-3 reflector not shown
- the pressure waveform produced by either the PEAA 120 or EH 110 source individually was measured using a calibrated polyvinylidene difluoride (PVDF) membrane hydrophone 124 (Sonic Industries, Halboro, PA) that had a frequency bandwidth of 20 MHz, a minimal rise time resolution of 11 ns and a sensitivity of 6.8 kPa/mV.
- PVDF polyvinylidene difluoride
- the PVDF hydrophone was scanned at 1 - or 2-mm steps, either along or transverse to the shock-wave axis.
- the output signal of the hydrophone was recorded on a LECROY digital oscilloscope 126 (Model 9314) at 100 MHz sampling rate.
