- W2002853889 abstract "Current understanding of mechanisms of shock wave (SW) action in shock wave lithotripsy comes almost entirely from laboratory testing. Past attempts to characterize lithotripter SWs in vivo have been hindered by difficulties in hydrophone alignment and physical constraints precluding precise mapping of the acoustic field. We adopted an ex vivo approach in which full-thickness segments of pig abdominal wall were secured against the inside surface of the Mylar acoustic window of a water-filled test tank coupled to a Dornier Compact-S lithotripter. A fiber-optic probe hydrophone was used to measure SW pressures and map the field in 2 mm steps in the focal plane. Peak positive pressure (P +) on axis was attenuated roughly proportional to tissue thickness (6.1% per cm, ~40% for a 5–6 cm body wall). Negative pressure (P−) was less affected. Shock rise time was unchanged (~18–20 ns). Although irregularities in tissue thickness affected SW focusing, step-wise mapping of the field showed no effect of the body wall on focal width (~6 mm with or without tissue). These findings suggest that apart from attenuation, the characteristics of the acoustic field for SWs passing through the body wall are remarkably similar to values collected in the free field.
