Abstract

A description is given of a soft flash X-ray system designed primarily for observing cavitation bubble clouds which are generated in Extracorporeal Shock Wave Lithotripsy (ESWL). This system consisted of a spectrum and image simulation system and two types of high-intensity single flash X-ray generators. The shock waves for ESWL were generated inside an ellipsoidal reflector by detonating a pellet of silver azide (AgN3). High-speed radiography was performed by means of delayed radiography, and the spatial and temporal distribution of the bubble clouds generated by underwater shock wave focusing were observed in pseudo-human tissue.
